UserWarning: SIMPLE-WARNING: Chip specification contained fidelity 1.0d0 > 1.

Issue Description

Several tests get this warning. It is not apparent why, considering the specs_dict in conftest.py does not contain any fidelities greater than 1.

How to Reproduce

To pick one example:

================================ 1 passed, 1 warnings in 0.10s =================================

Start with pyquil/tests/test_quantum_computer.py::test_qc and the specs_dict in conftest.py, then trace the warning reported at rpcq/_client.py:177. Determine where the fidelity value becomes 1.0d0 despite the test specification, and verify that the test no longer emits the warning while still passing.
