Update tests for new mocket version

Mocket 3.11.0 switched to a new package for parsing HTTP requests. This
changed the header normalization. Unfortunately, the library does not
seem to expose a method on the request object that normalizes the
header name before checking for it; as such, we normalize them
to lowercase ourselves.
