Cancel all legacy voicemail notification when SIMs are removed on multi-SIM devices

When the SIM is removed, telephony will signal cancel notifications on the "null" account (the framework doen't know what was there.). Previously this has no effect. In this CL, all legacy voicemail notifications are removed since all SIM will be removed together.
