Sometimes, devices may accidentally go offline during test with "device 'UUID' not found" error.
In this scenario,
you will got "'NoneType' object has no attribute 'readline'" AttributeError
when you call create_output_excerpts in teardown_test().
This PR checks _adb_logcat_file_obj is not None before calling readline().
An empty excerpt would be created at excerpt_file_path if device offline.
