Fix an internal server error when diffing patch sets (non-merge commit)

In specific constellations, users ran into an internal server error
which left log statements such as:
java.lang.IllegalStateException: nextB = 25; want 32

Add more tests to cover those situations and add a fix which avoids the
error. In one case, this still does not result in the absolutely correct
behavior but it's better than always running into a server error.
