Fix linting issues

Fix for issue #39 

Find instruction was throwing the following error message on windows
machine "find: invalid predicate `-wholename'". To test on unix-like.

Removed unused vars in tests. Added conjure function global instruction
in objectInit and arrayInit.
If you are happy with that, I didn't want to do it because I didn't consider it "elegant"... but I guess that my solution wasn't either.
