CSIStorageCapacity: prepare tests for enabling the feature by default

Defaults and validation are such that the field has to be set when
the feature is enabled, just as for the other boolean fields. This
was missing in some tests, which was okay as long as they ran
with the feature disabled. Once it gets enabled, validation will
flag the missing field as error.

Other tests didn't run at all.
