python3: disable check in PyThreadState_Swap

This check is triggered by nested pyuno PyThreadAttach instances.
The assertion is basically about having multiple PyThreadState instances
per OS thread.  Hopefully this is not a "real" problem and the other
checks in PyEval_ReleaseThread/PyEval_AcquireThread will find all "real"
problems.
