Allow repository URI to start with ssh:// to use ports different to 22

SSH repo URIs can be specified in two ways for jgit. ssh://user@host:port/path and a shorter one git@host:user/repopath.

This fix enables the usage of the former one. That enables the usage of ports different to port 22.

Note: As jgit supports another protocol named "git" directly, we should probably look for "git@" at the start instead of "git", as "git://" starts with "git", but is not an ssh protocol.
