Dash shows four columns on phone after disconnecting from monitor

[Michael Terry]

To reproduce:
- Boot a mako connected to an external monitor
- Disconnect from external monitor

Notice you now have four columns on the app scope instead the normal three.

Albert says this is because we determine column numbers when the scope opens and never reconsider it. We should make that logic dynamic.
