Title: Improved assertion message in `verifyNeedsDependencies`

In dev builds, the first failed assertion throws, with the result
that you only find out 1 of the missing dependencies in your
controller's needs list at a times. This commit collects all the
missing dependencies and then does one assertion listing them out
so you can address them all before kicking off your build, tests, etc
