fix [gratipay] test (#3303)

Not really sure what happened, but the test for the deprecated gratipay/gittp service has been failing for a while with a 404 badge not found error. For example

`AssertionError: label mismatch: expected '404' to equal 'gratipay'`

This tweaks the rout pattern so the test is passing again.
