OtherTests.generateFunctionIndex fails to detect UNNEST WITH ORDINALITY even though it is used in the Python tests.

It searches for an exact match: UNNEST WITH ORDINALITY
But the syntax is: UNNEST(<expr>) WITH ORDINALITY.

Running this test after adding the string containing Python test file names for function in CalciteFunctions.java fails with the following error:

[ERROR]   OtherTests.generateFunctionIndex:758 
� Runtime Could not find function UNNEST WITH ORDINALITY in ../../python/tests/runtime_aggtest/complex_type_tests/test_arr.py
