Validate that extra params + resources aren't provided
While working on creating an end to end test for tektoncd#168, @dlorenc and I had a very hard time determining why our pipeline wasn't working as expected - it turned out that we were using the wrong resource name in our `providedBy` clauses. This is the first of a couple follow up commits to add more validation: this one makes sure that extra resources are not provided (e.g. if you typo-ed a param with a default value, you may never know your param was being ignored). (Shout out to @vdemeester - I updated the reconciler tests both before and after his test refactoring, and it was nearly impossible to understand the tests before his builders were added: the builders made it waaaaay easier! 🙏 Follow up on #124
