Profile viewer: reset y limits when changing collapse function

[kecnry]

Description

This PR resets the y-limits of a profile viewer when the collapse function is changed (similar to what is currently done for normalize - the plotted data have changed in y, so the existing y-limits are meaningless).

@kecnry - we've fixed some of the CI issues recently so could you rebase to see if the failures here are real?

[kecnry]

@astrofrog - rebased but many are still failing. Is it possible the tests would need updating to account for this scenario? Or is there a reason I'm missing where this is not the desired behavior?

[astrofrog]

I'll investigate, thanks!

This turned out to reveal a subtle issue which was that state classes when used not in the context of a GUI were not subscribing to subset updates, so I've now fixed this properly. Let's see if this makes the CI happy now!
