ReplacePowerMockito: ensure mockito-core is added when PowerMock is removed (#920)

* Add failing test for missing mockito-core after PowerMock removal

When a project only has PowerMock declared and gets Mockito transitively
through powermock-api-mockito, ReplacePowerMockito removes the PowerMock
dependencies but never adds mockito-core.

Reproduces moderneinc/customer-requests#1926

* Replace PowerMock API dependency with mockito-core instead of just removing it

When a project gets Mockito only transitively through powermock-api-mockito,
RemoveDependency leaves no Mockito dependency at all. Instead of removing and
then adding (which runs into stale GradleProject marker issues with
AddDependency), use ChangeDependency to convert powermock-api-mockito directly
to mockito-core:3.x.

Handles both powermock-api-mockito (Mockito 1) and powermock-api-mockito2
(Mockito 2) artifact names.

Fixes moderneinc/customer-requests#1926

* Regenerate recipes.csv

* Add comment explaining mutual exclusivity of powermock-api-mockito artifacts
