Fix FindAndRunScript function

[dankmolot]

When CompileFile used, moonloader will act strangely, and will confuse itself and will enter script loading loop or even ignore existing compiled files telling gmod that files couldn't be found.

I need to remade this part and probably rethink when and how moon files should be compiled.
