Fix #2178

The error message is pretty terrible. We will see it only when there is no default behavior, so there must be at least 1 paramtrized mock.

I tried to show what we evaluated in order to reach that point where no filter matched. but the wording needs to be better, and well as the formatting of the invoked filters I think.

But then we should be able to re-use similar thing for Should -Invoke to show the history of execution, when failing should Invoke. To show the performed invocations.
