Do something with undocumented pass in GenericMethodWrapper._build_kwargs()

[yousefmoazzam]

A bare pass with no explanation isn't great if that condition is ever hit:

httomo/httomo/method_wrappers/generic.py

Lines 248 to 249 in 3276af4

	elif p in self._params_with_defaults:
	pass

Putting something here instead of a pass would be best, but if that can't be done, documenting why there is a pass here would be useful for developers' understanding.
