can't create new mapping with wizard from scratch

[Owen Williams]

I have a controller that is not supported by Mixxx. I'd like to start mapping by using the midi mapping wizard, but the Wizard button is disabled unless a mapping is selected. This is a paradox. A simple workaround would be to create a new preset called "Blank Midi Mapping" with nothing configured. (easy starter bug!)

Confirmed. I noticed it with the MIDI Through, though:
* enable MIDI Through, Apply
= Wizard button is not activated
* close + open preferences
= Wizard button enabled

maybe this and https://bugs.launchpad.net/mixxx/+bug/1945108
are related to incorrect isDirty(), see

([unchanged] mapping is reload when clicking Okay in any other page)

Is this on the main branch or 2.3? I am pretty sure we solved a regression with this during the 2.3 beta period, but it's plausible that refactoring on the main branch created a separate regression.

I noticed it on main.

btw the bug occurs also the other way around:
disable a controller, Apply and the Wizard button is still enabled and would also start the wizard (after being prompted to Apply the 'changes')

After a quick check I think it's just that the Wizard button needs to be updated in slotApply, not just in slotUpdate.
