core: TestContext2Apply_multiDepose_createBeforeDestroy incorrect logic

This test was re-using the same context to run three consecutive
plan/apply operations, which is not safe because we will accumulate more
planned changes with each change, creating duplicate entries in the diff.

Instead, to properly simulate a sequence of consecutive runs of Terraform
we must start with a fresh context each time, though still pass forward
the previous state which would in the real world be persisted via a state
manager between these runs.
