Check for presence of carrier app in Mobile Plan.

When the user chooses Mobile Plan in Settings, first do a check to see if
a valid carrier app for the current MCC/MNC exists. If so, launch that app
instead of checking for a provisioning URL or hoping for a DNS redirect in
the browser. If no such app exists, continue on as normal.
