Fix LoadControl for 1 phase connected EVSE (#110)

- If an EVSE is connected via 1 phase, `LoadControlLimits` should not
add empty data for non existing phases, otherwise this will lead to
invalid data for consumers. E.g. checking if any phase is active will
always fail, as these are always returning false
- Add more tests for Audi Mobile Connect setup with 1 phase
- Add more tests for Elli Connect/Pro Gen 1 with 1 phase setup
