fix(live-status-gw): issues with the currentPart and nextPart of the activePlaylist

About the Contributor

This PR is being opened on behalf of TV 2 Norge.

Type of Contribution

This is a:

Bug fix

Current Behavior

Sometimes the LSG would not send an activePlaylist topic update when the next partInstance changed in Sofie, due to some changes that don't affect the collection subscription being discarded by the PartInstancesHandler. Sometimes the pieces would be missing in currentPart and nextPart due to a similar issue in the PieceInstancesHandler. Pieces in nextPart were from the current partInstance.

New Behavior

PartInstancesHandler and PieceInstancesHandler notify the subscribers when relevant data changes so that the activePlaylist topic can send updates when needed. Pieces in the nextPart are from the next partInstance.

Testing Instructions

Set different parts as next multiple times in a row, and verify that each time the LSG sends an update containing the correct nextPart, including its pieces.
Verify that the pieces in the currentPart are present
