pymc3.py: explicitly set step method arguments

See merge request lscsoft/bilby!293

 - PyMC3 only applies the step_kwargs and nuts_kwargs arguments
   to the step methods if they are automaticallu allocated. Otherwise,
   it assumes you have already initialised the method with the
   required keywork arguments. This was not being done in bilby, so
   this patch fixes it and does explicitly initialise the step methods
   with values passed to step_kwargs or nuts_kwargs as required.
