Fix #7969: Preserve local view on aggregate mode exit

If local view was already active when aggregate mode was entered,
disable_aggregate_mode no longer toggles it off. The pre-existing
state is saved in was_in_local_view on BIMAggregateProperties and
only cleared if local view was entered after aggregate mode began.
