editablelabel: Properly clean up in dispose

Browse Source 
Unparenting the stack finalizes the entry and label,
but at least the label is available via the
gtk_editable_get_delegate API, and the a11y
implementation uses that at dispose time. So, clear
the pointers to prevent them from being dangling.

This was showing up as a segfault of the doc-shooter.
