Fix issue with ref deletion and global-refdb
Do not reuse `com.google.gerrit.server.restapi.project.DeleteRef` class
to delete ref because it operates with an high-level repository manager.
Using the high-level repository manager may be an issue in come cases
where it is wrapped, like in the multi-site setup (see [1]), with a global-refdb
and therefore may not be able to complete the REST-API successfully.
