Disabled fallback source triggers additional track updates (playlog POST)

Possibly this happens due to source.skip implementation.

To reproduce:

1. Play a fallback source: Metadata updates trigger correctly from this source
2. Switch to a queue source: Metadata updates trigger correctly from this source
3. Switch back to the fallback source: Two metadata updates get triggered
