Check that we are not overwriting a local repository when syncing.

Browse Source 
If a local git repository exists within the same folder as a new project that
is added, when the user syncs the repo, the sync will overwrite the local
files under the project's .git repository with its own symlinks. Make sure
that we do not overwrite 'normal' files in repo and throw an error when
that happens.
