Trim URL repository during import (BB-4523)

Hi,

When i tried to import a GIT repository from one of my own server (using GitBlit). There was an error during import :

{{{
/info/refs not found: did you run git update-server-info on the server?
}}}

The reason was a space at the end of the repository URL.

I think that you can just trim the posted value.
Not a Big issue but quite embarrassing.

I really like BitBucket !!!

Thanks,
Regards
