Add meaningful GUI error when migration fails

[lidel]

Some power users may run into situation, where repo version is higher than one supported by ipfs-desktop:

021-05-13T22:01:23.422Z error: [ipfsd] start daemon Error: Initializing daemon...
go-ipfs version: 0.7.0
Repo version: 10
System version: amd64/windows
Golang version: go1.14.4
 
 Error: Your programs version (10) is lower than your repos (11).
Please update ipfs to a version that supports the existing repo, or run
a migration in reverse.
See https://github.com/ipfs/fs-repo-migrations/blob/master/run.md for details.

IIUC this error lands in logs, but the user gets generic one with option to "restart" or "report github issue"
We should do better, and display console output to the user, so they can self-service.
