Align group reference from plugin with core group reference

I1160f1f55 added support to allow plugins to reference groups in
project.config but the way of referencing differs from what is done
in the core.

Even though the reference contains both group_name and group_uuid, it
was still required to have the mapping in groups file.

projet.config
  [plugin "somePlugin"]
    key = Group[someGroup/d6da7dc4e99e6f6e5b5196e21b6f504fc530bba]

groups
  3d6da7dc4e99e6f6e5b5196e21b6f504fc530bba    someGroups

Re-align group referencing with what is done all the other sections of
project.config to prevent having to put the group_uuid in both
project.config and groups file. Also this will make project.config more
consistent.

project.config
  [plugin "somePlugin"]
    key = group someGroup

groups
  3d6da7dc4e99e6f6e5b5196e21b6f504fc530bba    someGroup

This change is not backward compatible but searching[1] the open source
plugins, there is not a single use of GroupReference.fromString method
which should be used to load a group reference from project.config.
