Fix the build for git repositories with multiple remotes.
Summary:
When a git repository had multiple remotes, ${repository} will be set to a multiline string. This causes compilation errors in SVNVersion.inc.
Fix this by limiting the output of utils/GetRepositoryPath to the first remote (which is reasonably likely to be 'origin').
