Print supressed error message if it comes first.

odersky · odersky · commit abba939a7142 · 2015-04-13T16:06:10.000+02:00
An error message might be suppressed because it contains internal code. But
if it is the first one, we should still print it. Otherwise, we risk a scenario where
we see "2 errors" but none is printed.
