Fix selected room bindable being set to null regardless of the removed room

[frenzibyte]

Briefly discussed in discord. The bindable was supposed to be updated only when the selected room matches a removed room (therefore clearing selection), but was refactored at some point and the conditions appeared to be incorrectly removed (see 8222255#diff-6641e1f909bc58c5179c3c0b386be672449b434087378a72ee99557118db305aL103-R102). I cannot seem to find any positive/negative behavioural change caused by this.

I think you linked the wrong rev? I'd think 8222255 is where the issue started, no?

Edit: yeah the above rev is what you linked here even. Bit confusing but sure.

Yeah my bad.
