Change the name of the test from AirplaneMode.

The test is failing for me:

TEST-START test_settings_power_save_mode.py
test_power_save_mode (test_settings_power_save_mode.TestAirplaneMode) ... ERROR

It looks like it's waiting for the SIM to not be ready, but that is not the condition that this test expects. So the test is not currently written with the correct expectations, and I don't see how this test ever passed on a device.
