Energy Dashboard does not correctly sync

[garethparris]

The entities with a total state class don’t have a last_reset attribute. So every day when those values go to 0, they are treated as a negative cost. That is incorrect.

Those cost entities should either have been class total_increasing, or they should be total but have a last_reset attribute. The former is preferred.
