Auto refresh de-selected the selected incident on refresh

[clcollins]

When refreshing the incident list, the selected incident is de-selected. This prevents issues with the incident no longer existing, but when auto-refresh is turned on, kicks the user out of views that depend on an incident being selected (eg: view incident, add a note, etc)

The selected incident should remain selected throughout updates, and if not in an incident-dependent view, the table should de-highlight a row if there's a selected incident.
