561 – Incorrect duplicate error message when trying to create instance of interface

interface D
{
 void foo();
}
void main() {
	D d = new D();
}
The above code errors out with:
asdf.d(7): Error: cannot create instance of interface D
asdf.d(7): Error: cannot create instance of abstract class D
Huh? Abstract class? That's an interface, not an abstract class. The first error message is expected, the second is both incorrect and superfluous.

Damn typos.

This should be easy to fix. expression.c, line 2756, change from:
if (cd->isAbstract())
To:
else if (cd->isAbstract())

Fixed DMD 1.019 and 2.003
