ph install adds the ph command incorrectly in .zshrc

ph install adds the following in .zshrc 

```
# ProjectHelper
ph () { eval $(/home/guy/go/bin/projecthelper go $@) }
```
This makes running ph always do ph go, so commands like ph clone or ph update will not work. 
Changing the line to 
```
# ProjectHelper 
ph () { eval $(/home/guy/go/bin/projecthelper $@) }
```
will resolve the issue.
