tests: Add a test case for batteries with zero power draw

Browse source 
Make sure that the issue reported in #7 and #44 is fixed.
The mocked battery has a zero power_now attribute and a non-zero legacy
current_now attribute on purpose, to detect if upowerd tries to read
current_now if the power_now value is small.
