errors.sin passes during "make installcheck", breaking "make distcheck"

[Christian Speckner]

All of a sudden, "make distcheck" breaks for me with errors.sin passing without an error and the output of WHIZARD being

Obviously, sqrts somehow gets set, triggering this misbehavior. Strangely enough, it behaves as it should during "make check" (or when TESTFLAG is present), giving a nonzero return code and printing

Somehow I've got the feeling that this regression was introduced in r1554, but then again, I might well be wrong :)

Trivial error: If sqrts is not initialized, it can have any value, not just zero.

Fixed in r1571.
