I guess this one is simpler to maintain, also notice that iterating in
the data->interfaces to check if there are no other pending_prop has
almost the same effect as process_property_changes, what would make a
difference would be to prevent process_changes but that has to run
anyway to propagate the interfaces added/removed. Also notice that
data->pending_prop is clear earlier than the original fix for
duplicated signals, the one that introduced this problem, that way we
don't reintroduce the original problem.
Regarding the commit message, we usually avoid BlueZ specific
description there as gdbus is shared with other projects.
