Resend the EVENT_RESUME_NOW_FOREGROUND_CALL message after onCallHeld.

Where the MT call is answered and terminated at the same time while there is an ongoing MO call, an ImsReasonInfo.CODE_LOCAL_ILLEGAL_STATE exception occurs after calling #resumeForegroundCall due to a timing issue.
If Call is not pendingHold, trigger #resume.
If Call is pendingHold, send the EVENT_RESUME_NOW_FOREGROUND_CALL message again after onCallHeld is called.
