Clean up PlayerWrapper exception log

PlayerWrapper throws Exception if getters is called in the
STATE_IDLE. In that case, log may print 50+ lines of stack
traces. It's verbose and can be considered as serious issue.

This CL include folloing changes
  - Change to use ExoPlayer's log class
  - Adjust log level, because it would be consumed by caller
  - Leave log when the debug flag is turned on.

Another CL will remove exceptions between PlayerWrapper and
and SessionPlayerConnector, not to use Exception for ordinary
control flow as the Effective Java suggests.
