actionmuxer: avoid duplicate and recursive work

If we've already done the tracking into the parent muxer, there is no need
to do it again. This can save a great deal of recursive work when adding
items to the muxer.

This makes showing the context menu in gnome-text-editor repeatedly fast
even as spelling corrections are changed.

It is likely that this could fix #4422 as well.

Fixes #4519
