[Test] Rename pytests to <something>_test.py; rename test-cases

To be consistent with conventional test-code naming conventions,
this commit renames existing pytest files to <something>_test.py
E.g., test_gen_loc_files_basic.py -> gen_loc_files_basic_test.py

Individual test-cases are already named as test_<something>;
E.g., in above test file, test method is named: test_loc_main_script_dir()
and so on.
