Centralize VVM error Processing

To prepare for vendor specific error codes every error that is written to
the voicemail status table is centralized to the VoicemailProtocol,
which determines what error code will be actually written.

+ Use PhoneAccountHandleConverter to convert subId instead of PhoneUtils.
  PhoneAccountHandleConverter still uses PhoneUtils under the hood but
  it will be changed to using public API in the future.
