Remove unused kwargs from query_by_values, filter_and_sort

[Seth-Rothschild]

There are 5 keyword arguments to query_by_values and filter_and_sort that were unused outside of tests:

• return_sorted=False
• start=None
• end=None
• random_seed=None
• shuffle=False

This PR removes those arguments, the associated docstring segment and the two tests that were testing return_sorted.
