Don't encode IDs at all

The encoding of IDs (to acceptable URL values) is done in python-gitlab,
so don't do that here. Between python-gitlab 2.6.0 and 2.7.0 the
encoding implementation changed (to handle more cases, for Debian
repository-naming-rules) which breaks when it is handed an already-
encoded ID.
