repo_groups: fix deletion of subgroups
Deletion of a repository group that has a parent group (i.e. is not at the
root of the repository group tree) failed as follows:

In the reference 'gr.parent_group', 'gr' is an SQLAlchemy object referring
to the group being deleted, and 'gr.parent_group' is a lazy reference to its
parent group. The 'lazy' means that the parent group object is not loaded
automatically when 'gr' is assigned, but instead will be loaded on-the-fly
when the parent group is actually accessed. See [1] and [2] for more
information.
The problem was that the lazy 'parent_group' attribute was accessed _after_
deleting the database object it was part of.
Fix this by obtaining a handle to the parent group _before_ deleting the
subgroup.
