FIX gogs migration if gogs is hosted at a subpath (#3572)

Browse source 
Also add a test for GogsDownloaderFactory.New() to make sure
that the URL of the source repository is parsed correctly.

When the source gogs instance is hosted at a subpath like `https://git.example.com/gogs/<username>/<reponame>` the migration fails.
This PR fixes that.
