Link with VBAHELPERLIB too
Link with VBAHELPERLIB too

I don't know why we need to link with VBAHELPERLIB, it is supposed to
contain just inline methods that get compiled in from the headers and
not needed to be linked with, says Noel.

If it is just here in a unit test, no big deal. If it turns out that
this should and can be fixed in some other way, this commit can be
reverted.
