Make the 'Committing revision...' notification visible for URL URL copies,
where it was explicitly hidden before... which was the standard behavior
before we added url support for notifications a few years ago.

The behavior was made explicit when the notification setup was generalized
for all svn commands.

* subversion/svn/copy-cmd.c
  (svn_cl__copy): Use standard behavior for url-url copies.

* subversion/tests/cmdline/blame_tests.py
  (blame_output_after_merge): Expect notification.

* subversion/tests/cmdline/copy_tests.py
  (url_copy_parent_into_child): Expect notification.

* subversion/tests/cmdline/merge_tests.py
  (simple_property_merges,
   merge_old_and_new_revs_from_renamed_file,
   merge_with_auto_rev_range_detection,
   merge_added_subtree,
   dont_merge_revs_into_subtree_that_predate_it,
   set_up_renamed_subtree,
   set_up_natural_history_gap): Expect notification.

* subversion/tests/cmdline/merge_tree_conflict_tests.py
  (merge_replace_setup): Expect notification.

* subversion/tests/cmdline/switch_tests.py
  (delete_subdir,
