Add missing addCleanup of _delete_group_snapshot

In test_group_snapshot_create_show_list_delete, no addCleanup
of deleting group snapshot is added after create_group_snapshot,
this is to add it.

Besides, since this is a simple patch, so just do some trivial
fixes at same time:
1. use list comprehension if possible
2. put statements in one line if possible
