Delete a canvas tooltip after we've finished with it

Browse Source 
All canvas objects share just one tooltip object which is based around Gtk::Label. The Label expands if the current tooltip text is wider than the previous text. However, it doesn't shrink again if the next tooltip has shorter text. Eventually, this results in some very strange looking tooltips (especially in Mixbus where they're used quite extensively).

Deleting the object after use will force a new object to get generated next time (at the correct size). There's still only ever one object per canvas but it's no longer persistent.
