Behaviour from auto update of "Up next" playlist

[fredsleeve]

Discovered some odd behaviours, please check.
Automatic update of Up next needs to be enabled for this.

Message "Up next has been updated by" does not appear:

1. Create a new playlist add several episodes
2. Start playing an episode so Up next will be update (message "Up next has been updated") appears
3. Go to Up next and e.g. remove an episode (message "will not be updated anymore" appears)
4. Go back to your created playlist and start playing again
5. Now: No message appears that this Up next has been from this playlist, but it has been updated
6. If you play a single episode from a podcast directly, the message appears
7. The message also appears when you clear Up next manually and start playing from you playlist

Update (sync) symbol does not change:

1. Make sure Up next is update from a playlist
2. Remove an episode via swipe or long press -> message "will not be updated anymore" appears
3. I would expect that sync symbol changes like when reordering the episodes in the list.

Playing a single episode sometimes gets appended to Up next and sometimes not:
I cannot reproduce it, but sometimes an episode will be appended to Up next when start playing a single episode from podcast and sometimes not (then only the currently played episode is in Up next).

Thanks very much for the detailed bug report. Will fix the sync/link icon issue in the next update.
