python3-hypothesis: upgrade 6.14.8 -> 6.15.0

6.15.0 - 2021-08-22

This release emits a more useful error message when @given() is applied to
a coroutine function, i.e. one defined using async def (issue #3054).

This was previously only handled by the generic return_value health check,
which doesn’t direct you to use either a custom executor or a library such
as pytest-trio or pytest-asyncio to handle it for you.

6.14.9 - 2021-08-20

This patch fixes a regression in Hypothesis 6.14.8, where from_type() failed
to resolve types which inherit from multiple parametrised generic types,
affecting the returns package (issue #3060).
