[autotest] Update Servo label exists method

Previously ServoLabel checked if the _servo_host object was not None.
That wasn't always true since during the reset job, the _servo_host
object does not get created since 'try_lab_servo' isn't true when
creating the host.  This uses the method that servo_host module uses
to check for prior to creating the _servo_host object.

BUG=chromium:609143
TEST=locally with chromeos1-row5-rack6-host1
