Move thrown.expect() right before the throwing statement

Browse source 
aka regexing for fun and profit.

This also makes sure that there are no statements after the
throwing statement, since these would be dead code. There
were a surprising number of places with assertions after
the throw, and none of these are actually triggered in tests
ever. When I found these, I replaced them with try/catch/rethrow
which makes the assertions actually happen:

before:

// This is the ExceptionRule that checks EppException marshaling
thrown.expect(FooException.class);
doThrowingThing();
assertSomething();  // Dead code!

after:

try {
  doThrowingThing();
  assertWithMessage("...").fail();
} catch (FooException e) {
  assertSomething();
  // For EppExceptions:
  assertAboutEppExceptins().that(e).marshalsToXml();
}

To make this work, I added EppExceptionSubject.
