catch lstat ENOENT to set destDir when using includesPath

[hollanddd]

I'm not convinced that this is the most elegant approach and am open to further discussion. As it stands the ternary operator will exit when fs.lstatSync() throws the ENOENT error. In that case I set the destDir to the optimized path plus the included path. I tried fs.lstat() but I ran into async issues there. I also entertained the idea of using fs.exists() as it would have been a small addition to the already existing ternary operator. However, it's deprecated causing me to look for a new solution.
