Remove hypothesis dependency (#2774)

Summary:
Pull Request resolved: #2774

Context: Hypothesis is not commonly used in Ax and is not part of the `UNITTEST_MINIMAL_REQUIRES` dependencies (although it is part of `UNITTEST_REQUIRES`). It is used in only one benchmarking test. Removing it will make it easier to build an environment that can run benchmark tests. We could have a broader discussion about removing it from Ax entirely.

This diff: Changes a unit test to not use hypothesis
