Title: Fix to check if device_path set to empty string

- Trove config does not allow the config option 'device_path' to be set to None.
It has a default String value and setting an empty value in trove.conf will set the config option to empty string.

- This causes trove resize_flavor in models.py to throw an exception.

- Fix mad to also check for empty string in device_path
