mango: fix `text` index creation in tests

In `16-index-selectors-test.IndexSelectorText.test_uses_partial_index_with_non_indexable_selector`,
the parametrization of the `create_text_index()` is incorrect.  It
passes `["location"]` as a set of fields to index, but that is
actually taken as an analyzer.  It is probably a result of
copy-and-pasting over from the `json` index creation above where
the first parameter to the corresponding function is the list of
fields.
