Campbell Barton b25eefbf9a Fix #122132: Crash canceling nested popups
Moving the cursor away from the extensions "Add Repository" popup
could crash because the "Repositories" popover was closed while the
popup it created remains open.

Resolve by clearing wmEventHandler_UI::context.region_popup
which match the freed region, following similar logic already used by
WM_event_modal_handler_region_replace.
