Fix bug where client sometimes fails to receive current user's profile.

[dwrensha]

Fixes #15.

[dwrensha]

Actually, please hold off on merging this. I just noticed that it breaks the little green presence indicators by the user avatars. :/

[dwrensha]

This should be OK now.

Hi,
using Wekan standalone version (not Sandstorm) with node version 0.10.48, when I use these scripts to rebuild and run wekan:

# wefork-build.sh

rm -rf wekan
git clone https://github.com/wefork/wekan
cd wekan
# OPTIONAL: test pull request
git checkout -b dwrensha-profile-bugfix devel
git pull https://github.com/dwrensha/wekan.git profile-bugfix
# THESE 2 ONLY ON FIRST INSTALL
#sudo npm install -g node-gyp
#sudo npm install -g fibers
npm install
meteor update --release 1.3.5.1
rm -rf .build
meteor build .build --directory
cd .build/bundle/programs/server
npm install
cd ../../../../..
echo "Build done. Starting wefork server."
./wefork.sh

# wefork.sh

cd ~/repos/wekan/.build/bundle
export MONGO_URL='mongodb://127.0.0.1:27017/admin'
export ROOT_URL='https://wekan.example.com'
export MAIL_URL='smtp://user:pass@mailserver.example.com:25/'
export PORT=9595
node main.js

I use this Caddyfile on Ubuntu 16.04 server:

wekan.example.com {
        proxy / 127.0.0.1:9595 {
                websocket
        }
}

And this service file for Caddy:

# /etc/systemd/system/caddy@.service

; see `man systemd.unit` for configuration details
; the man section also explains *specifiers* `%x`

[Unit]
Description=Caddy HTTP/2 web server %I
Documentation=https://caddyserver.com/docs
After=network-online.target
Wants=network-online.target
Wants=systemd-networkd-wait-online.service

[Service]
; run user and group for caddy
User=user
Group=user

RestartSec=10
; create a private temp folder that is not shared with other processes
PrivateTmp=true
; limit the number of file descriptors, see `man systemd.exec` for more limit settings
LimitNOFILE=8192

[Install]
WantedBy=multi-user.target

Service was installed with:

sudo systemctl daemon-reload
sudo systemctl start caddy@user
sudo systemctl enable caddy@user

A) When I login normally, it logins to Wekan

B) But when I did this:

1. Create public board on Wekan that is running behing Caddy webserver
   on url:
   https://wekan.example.com/b/o7LAibK2RYwpTAqEj/test

2. Click login link on public board

3. Try to Login, did not work

4. I got this error shown below on Firefox Javascript console, and was unable to login:

6. When I did
   6.1) Rebuild wefork
   6.2) Go to board public link
   6.3) Used login link on board to login
   6.4) It did not show any errors on serverside anymore, but on clientside Firefox Javascript console it showed these errors below
   6.5) Although login button did not work at first, when when checking source code I noticed it had logged me in anyway to All boards page.

Ah, interesting. I was able to reproduce that error. I've added a commit that avoids it, but I'm going to close this PR in favor of #25.
