Interferes with gulp-uglify

I get this error only when using gulp-remove-use-strict.

Start by reproducing the reported pipeline using gulp-remove-use-strict with gulp-uglify, then inspect the GulpUglifyError stack trace and the referenced minifier behavior. Done means identifying the incompatibility and confirming that the same JavaScript can be processed successfully with both plugins.
