Enable debug mode in tests.

Debug mode allows route integration tests to raise explicit exceptions on
errors, instead of returning error pages. Some portions of the test
suite need to be able to ignore exceptions (the response is not under
test) so they use a separate pytest fixture version of the app and
client that are configured with debug disabled, as it would be in
production.
