Tests are failing due to hypothesis filtering

[mtelka]

I do see three test failures with the same error reported:

__________ TestHypothesisStrategies.test_hostname_labels_valid_ascii ___________

self = <hyperlink.test.test_hypothesis.TestHypothesisStrategies testMethod=test_hostname_labels_valid_ascii>

    @given(hostname_labels(allow_idn=False))

E   hypothesis.errors.FailedHealthCheck: It looks like this test is filtering out a lot of inputs. 8 inputs were generated successfully, while 50 inputs were filtered out.
E   
E   An input might be filtered out by calls to assume(), strategy.filter(...), or occasionally by Hypothesis internals.
E   
E   Applying this much filtering makes input generation slow, since Hypothesis must discard inputs which are filtered out and try generating it again. It is also possible that applying this much filtering will distort the domain and/or distribution of the test, leaving your testing less rigorous than expected.
E
E   If you expect this many inputs to be filtered out during generation, you can disable this health check with @settings(suppress_health_check=[HealthCheck.filter_too_much]). See https://hypothesis.readthedocs.io/en/latest/reference/api.html#hypothesis.HealthCheck for details.
