Unit test for reverse calculation (#2483)

Add new test checks the behavior of the `thermal_cluster` when the
generation behavior is forced to no generation.
Verify the `thermal_cluster` behavior when `tsGenBehavior` is set to
`LocalTSGenerationBehavior::forceNoGen` and the time series is filled
with a constant value.
