tox: Update hypothesis/hypothesis-pytest to 1.10.0

This is just a bugfix and performance release, but it changes some semi-public
APIs, hence the minor version bump.

- Significant performance improvements for strategies which are one_of() many
  branches. In particular this included recursive() strategies. This should
  take the case where you use one recursive() strategy as the base strategy of
  another from unusably slow (tens of seconds per generated example) to
  reasonably fast.
- Better handling of just() and sampled_from() for values which have an
  incorrect __repr__ implementation that returns non-ASCII unicode on Python 2.
- Better performance for flatmap from changing the internal morpher API to be
  significantly less general purpose.
- Introduce a new semi-public BuildContext/cleanup API. This allows strategies
  to register cleanup activities that should run once the example is complete.
  Note that this will interact somewhat weirdly with find.
- Better simplification behaviour for streaming strategies.
- Don't error on lambdas which use destructuring arguments in Python 2.
- Add some better reprs for a few strategies that were missing good ones.
- The Random instances provided by randoms() are now copyable.
- Slightly more debugging information about simplify when using a debug
  verbosity level.
- Support using given for functions with varargs, but not passing arguments to
  it as positional.
