add unit test to check for plurals in routes

[Joseph Heck]

wishlist item (simple, low-hanging-fruit)

this is maybe meta, but if anybody wants to back-burner it, i'd love for some sort of check in the tests that checks for the word "condition" instead of "conditions" in any of the routes calls and "methods" instead of "method" in the same call

we've been bit multiple times already by forgetting which one is plural and not checking

it is small though, just would be a nice regex for somebody

    Raise if we see incorrect keyword args "condition" or "methods"

    Fixes bug 927879

    We crawl the AST of the set of modules that make routing calls, looking
    for keyword arguments called "condition" (should be "conditions") or
    "methods" (should be "method"), and raise if we see any.
