Allow incompatible mixed scala versions 

The zinc scripted project depends on all of the compiler bridges. As a
result the introduction of the strict scala binary version check in
f8139da192 broke zinc scripted. This
commit reverts to the old behavior in the non scala sandwich case.

I also switched to a for comprehension instead of a pattern match
because this is a rare case where I think it made the code significantly
more readable.
