base-call: ACTIVE after start() if detailed transitions unavailable

The most detailed call state transition flow for a new outgoing call
would be:

  UNKNOWN -> DIALING -> RINGING -> ACTIVE

But, if the modem doesn't support reporting intermediate states
(e.g. DIALING or RINGING) then a successful start() should imply
getting into ACTIVE state right away.

For now, only the Huawei plugin implements the detailed transition
support, so make them configurable via call object properties.
