OmniBar.refreshState: Don't layoutIfNeeded if... not needed

Task/Issue URL: https://app.asana.com/0/414709148257752/1208881366194997/f

Description:

OmniBar.refreshState is crashing when called as part of setting up the initial UI stack. It's specifically the layoutIfNeeded call that is crashing so I'm going to see if removing this when initially creating the views has an effect. After all, it shouldn't be needed in that case.

Steps to test this PR:

1. Launch the app a few times, altering the text in the OmniBar each time.
2. Generally try breaking this.

Overall this works for me, though I'll leave it to you regarding whether we want to proceed with this change since per discussion in Asana it's looking like this crash has an unrelated cause.
