Use new instances of PreCallAction on activity resume

Previously the same action instance is used every time the PreCallActivity is resumed. This causes some state to be retain, for example the isDiscarding state on CallingAccountSelector prevents canceling the next dialog to abort the call.

Actions should not retain state between activity life cycles.
