switch TelecomManager List getters to ParceledListSlice

It was shown that given a large phoneAccountHandles that are
over 1 mb, a TransactionTooLarge exception can be silently thrown
causing an empty list to be returned.

In order to prevent this behavior, all Lists that return a
PhoneAccountHandle or PhoneAccount have been switched to
ParceledListSlice.
