layout.get doesn't find any entities when passed a numpy.int64 value for run

When doing a layout.get(), if the type of the run argument is np.int64, it fails to find any entities. Here’s a minimal reproduction using pybids test data:

And before anyone suggests that the solution is to avoid passing int64s as run numbers, notice that get_design_matrix returns an int64. I’ve reproduced the above results with both 0.9.2 and 0.9.3.

Also, that solution precludes having any other method directly call _build_file_query unless type enforcement code is replicated there. There’s a current todo to have to_df directly call _bild_flie_query.

You could crib the try except structure from my pr to deal with cases when lists are passed. The tests in that PR also check list cases.
