voicecall: fix callheld indicator for PTS 

Fix PTS test TP/TWC/BV-03-I [Call Waiting- Hold Active/Retrieve
Waiting Call or Held].

PTS test fails after receiving intermediate update of callheld indicator
with value 0 (no held call) before it receives update to value 1
(active and held calls). This is due to the non-atomic update of calls
status after call swap (moving first call to active state before moving
second one to hold state).

HFP 1.5 spec specifies that an update of callheld indicator to 1 should
be sent after AT+CHLD=2 command.
As oFono emulator sends +CIEV only if the indicator value changes, we
need to use an intermediate state for callheld indicator (2, all calls on
hold).

So, in case of multiple active calls, or an active call with an active
mutiparty call, force update of callheld indicator to 2.
