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.

The / is escaped by normalize_url() it seems, but that's not appropriate
for getting repositories in namespaces (e.g. sdk/git-lab becomes
sdk%2Fgit-lab, and then that % is escaped again in python-gitlab and
the repo isn't recognized). Unescape it, The 'safe' value for quote_plus()
is different from plain quote(), leading to / -> %2F conversions
(too early) which we don't want.

Fixes #12
