AttributeError: query has no index making query.execute fail in certain boolean combinations

[reebalazs]

The BoolOp does not have an index property, but execute checks that for the first index. So If the first query itself is composed by another boolean, it will fail.

I don't know if the index is really necessary here, I just made the method to a classmethod so it can be called without requiring an index attibute.

I demonstrate some tests, if the code part is reverted then test_execute_first will fail, while test_execute_second passes.

Going more down in testing execute requires the change of the mocking at existing tests.

ERROR: test_execute_first (hypatia.query.tests.TestExecute)

fix-4-attributeerror-index contains the test + proposed fix
