bug(ui): stage phase icon + tooltip missing for some phases

[krancour]

In this particular case, the Stage was in the new (as of #2762) Failed phase, so the UI not being prepared for that wasn't surprising, but I believe I've seen this occur many times prior to #2762. (I have a hunch that no phase (""), which is possible for a brand new Stage, may be unaccounted for.)

@krancour thats Stage health status icon. Ok this UI code was a year ago and I think there was not "phase" initially? Or maybe health and phase had some correlation?

Anyways this needs to be changed if thats the case.

[krancour]

@Marvin9 you're right. I have my wires crossed here. That icon is for health, and not for phase, as you correctly point out.

Health can legitimately be nil, especially for a brand new Stage that has not had any Promotions yet (or hasn't had any successful Promotions yet).

I wonder if nil health is the source of this.

[Marvin9]

Yes nil health is the issue. But I think we should show both.. stage health + stage phase right?
