places sidebar: Preserve ::populate-popup functionality

Browse Source 
We "fix" this signal the same way we did for GtkEntry and
GtkTextView: slightly change the signature so that the passed
widget may be a container other than a GtkMenu, and add a
property to explicitly opt in to receiving the signal in
this case.
