InCallUI not dismissing after end call is clicked

In MT InCallScreen, the customMessage dialog
which appears when user tries to reject a call
with message, is not set to null when user
cancels the dialog.
InCallUIActvity is not finished if there is any
pending dialog which is not null and hence this
issue is seen.

Set the dialog variable to null once the dialog
is cancelled by the user.

MSIM(DSDA): Ensure phone screen wake up on DSDA incoming call

In case of an incoming call on one sub with a live call on another sub,
force InCallActivity to finish() if the screen is off. This is required
since the screen will wake up only when InCallActivity is created.
Also cancel the on going InCall notification and notify the new
notification so that the full screen InCall intent is launched.
