Merge lp:~jml/testtools/expected-exception-791889 into lp:~testtools-committers/testtools/trunk

[Jonathan Lange]

This patch *actually* fixes bug 791889. Really.

In https://code.launchpad.net/~jml/testtools/matches-exception-791889/+merge/68595, I had assumed that the bug was about MatchesException. Luckily, the changes in that branch were also worthwhile, and made this branch much easier.

What we do here is make ExpectedException delegate to MatchesException for its logic. Neat, huh?

Also took the opportunity to tweak AfterPreprocessing so we can use it "silently", such that it doesn't leave a trace of itself in the mismatch. For the cases here, it actually makes the errors clearer.

Looks nice to me.
