Remove ability to enable/disable phoneaccounts (3/6)

Enabling/disabling of phone accounts was only used for SIP accounts and
is no longer necessary for the purpose it was put in.
- Remove all references to enabling/disabling phone accounts
+ Rename getEnabledPhoneAccounts to getCallCapablePhoneAccounts
