on startup explicit dock faulty moving onPrimary
--multi-screen fix for explicit docks. There were
cases that explicit docks during startup were
moving to onprimary screen even though they shouldnt
based on the new multi-screens implementation.
Bug was tracked down at a faulty series of signals
that were overwriting dockView config values
to default values and that was creating the fault.
- one more fix for multi-screens, a missing return
statement in case an explicit dock is called and its
edge at that specific screen is occuppied by an
onPrimary one.
BUG: 398219
