convert state to tuple explicitly when setting python random state

[awaelchli]

What does this PR do?

Fixes #9400

The changes in this PR should be a no-op as the state should already be a tuple. #9400 was reported on slack, not reproducible, but adding the tuple conversion doesn't hurt and resolves a user's issue for testing out the FT feature.
