Override `SmartFake.toString` to be super-verbose

Ideally I'd like it to throw, but I found that some tests use
these fakes as throw-away values: they got rendered in some HTML
or logged somewhere but never checked by the test.

Changing `toString` to throw forces such tests to add meaningless
expectations, which makes tests less readable.

So instead of throwing I decided to make `toString` just convey
the same amount of information that the exception has. This way
if the test doesn't care about the value, it will keep passing.
And if it does care, test failure will contain useful information,
suggesting what needs to be stubbed.
