test: refactor common.expectsError
This completely refactors the `expectsError` behavior: so far it's
almost identical to `assert.throws(fn, object)` in case it was used
with a function as first argument. It had a magical property check
that allowed to verify a functions `type` in case `type` was passed
used in the validation object. This pattern is now completely removed
and `assert.throws()` should be used instead.

The main intent for `common.expectsError()` is to verify error cases
for callback based APIs. This is now more flexible by accepting all
validation possibilites that `assert.throws()` accepts as well. No
magical properties exist anymore. This reduces surprising behavior
for developers who are not used to the Node.js core code base.

This has the side effect that `common` is used significantly less
frequent.
