* Added test for device matching
Mocking the scanning and testing the connect() of each backend would be
better, but that requires more refactoring with prior agreement.
Added unittest2 dependency for subTest support, other solutions are
available.
* Fixed matching for Move Hub
If other BLE devices are around, an exception occurs on hub_mac.lower() if
default hub_mac (None) is used.
