What I did
Ape shows you all compiler errors across compilers.
That is great, except when there was only a single error, thus causing a pointless exception being thrown on the stack.
How I did it
if len(errors) is just 1, just raise that error instead.
How to verify it
Compile with 1 compiler failing - should just see the custom
Compile with 2 compilers failing - should see them amassed
I added tests for both of these cases.
