Fix for no @name scripts

* Crashes the server when removing or never existing `@name` but localized ones exist
* Not entirely sure why one needs to `encodedURI` and the other `decodeURI` but redirect has issue ... possibly a current *node* issue
* Change text to import since it's not uploading a script technically

Additionally applies to OpenUserJS#200, OpenUserJS#226 edge case, and a bit from OpenUserJS#655 detection
