Fix failing tests after previous commit

Fix failing tests after previous commit

After the changes, the weaver's behaviour is now slightly different, but
not actually buggy. Actually, in one case there is now a weaver warning
for a non-matching pointcut which should have been there before, but was
not. I.e., things have improved and the tests are even a bit better now.
