git-sync: use refspec instead of --prune-tags

[edvbld]

Hi all,

please review this small patch that uses a refspec instead of --prune-tags for
GitRepository.fetchRemote. The flag --prune-tags was introduced in Git 2.17
and we want to support older Git versions, so I opted to use a refspec instead
to achieve the same effect.

Testing:

• Manual testing of git sync on Linux x64

Thanks,
Erik
