AudioPolicyManager:Fix that the track of start in a call does not

switch devices correctly after the call hangs up.

When the SIM card call is disconnected and the setPhoneState function
is called to reselect the device for tracks that were started during
the call, calling the getNewOutputDevices function with the parameter
fromCache set to true may result in unexpected device selection in
certain situations.

For example: During a SIM card call, an alarm sounds. At this point,
the alarm uses the earpiece as the playback device. After ending the
call, when setPhoneState is called here to select the output device
for the alarm playback, due to fromCache being set to true, the selected
 device remains the earpiece rather than the expected speaker.
