This adds Alert annotations for alerts that seem intentional by the test
but has not been annotated with 'NOT OK', or the comment was in the wrong
place.
In a few cases I included 'Source' expectations to make it easier to see
what happened. Other 'Source' expectations will be added in bulk a later
commit.
All the filtering is now done in `getALikelyCallee`, to which I have also added an additional parameter that improves the join in the `select` clause.
I've also simplified the alert message to no longer use `toString`, which isn't meant for alert messages anyway. (This is an old query.)
