Fix voicemail SIM card name unknown after unlock PIN.

Reproduce Steps:
1. Power on mobile with PIN.
2. Unlock PIN and receive a voicemail message.
Solution:
Voicemail message is received before SIM loaded, so SPN cannot
be shown on the voicemail. To fix, after SIM loaded, refresh
voicemail notification.
