failed playlist creation causes constant warnings

[simon-weber]

On a look through sentry I noticed one of the most frequent errors is from this line. It seems to be mostly from a handful of users where a playlist create failed, leaving an orphaned local autoplaylist that causes this warning on every sync.

I'm leaning towards just deleting the local autoplaylist rather than retrying to create the remote one. There is a chance this will delete a playlist people are using if we failed to persist the remote id, though it seems pretty slim.

You know, it's probably better to detect this and put something in the UI so users can decide what to do about it. It's easy to manually fix (by just duplicating the playlist), and automating it could lead to all sorts of runaway situations (eg duplicating forever because something else is preventing creation).

This can also prevent syncing in cases where the failed autoplaylist gets linked:
