Bug: lists update before loading children when getting new values

[gdorsi]

Using the MusicPlayer from two devices I've got into this error:

TypeError: Cannot read properties of null (reading 'id')

To reproduce:

• Log with the same account on two devices
• Add a new playlist

Result: the other device crashes with the "Cannot read properties of null (reading 'id')" error
