Test files in testdata/workloads/functional-query/queries/QueryTest
are parsed by test_file_parser.py, which used to ignore everything
before the first ==== line as a file header. This change fixes all
affected files.
This change also modifies the test file parser to forbid headers
starting with what looks like a subsection title ('----'), which
should prevent the reintroduction of similar errors in the future.
