request.getfixturevalue(name) does not work with async fixtures

[Slarag]

Current Behavior: Calling request.getfixturevalue(name) with the name of an async fixture raises a RuntimeError.
Expected Behavior: Calling request.getfixturevalue(name) with the name of an async fixture should initialize the fixture correctly.
