Clean removal of entities

[astrandb]

Improved handling of the unselecting of entities and the following cleanup.

I cannot verify that it works for eq-sensors since I don't have access to an Equalizer.

For me, the binary_sensors did not get created directly after the update, I had to change the settings to remove one binary_sensor and add it again. Or that was what I did at least to make it work again.

I also get an error when the equalizer status sensor is updated:

Sorry I do not have time right now to dig deeper.

@olalid I can't reproduce the issue with binary_sensor. Greatful if you can pinpoint when it happens. Unfortunately it is difficult do debug equalizer related problem when you haven't got one.

[olalid]

Yes, I understand that it is difficult to understand with the limited info I provided.

Great job @astrandb

Problem solved.

[olalid]

Hold on, I just discovered that the removal of equalizer sensors does not work for some reason. Investigating...

[olalid]

I fixed the equalizer removal bugs and merged to this branch.

Looks good

@olalid I don't know what happened when you added your fix. Suddenly this PR contains some 15 commits from you that seem to be old and irrelevant here. The resulting code is OK but I suggest that you check so you base your changes on correct branch.

@fondberg @tmjo I think this PR is as good as it gets for now. I should be squashed & merged.

Yeah, I am not a git guru, so I messed up a bit I guess.
