Title: Don't finish activity when launching dialer

If you try to dial someone who doesn't have the app installed, canceling will close the application. Desired behavior would be to take the user back to the previous screen, not close the app completely.

This mimics the stock dialer behavior. Free to decline if there is a security reason it works this way =)
