Repair User Flagging route
While I'm in here remove `@namespace` check for flagging a script... this fixes previously mentioned unflagging of a script

Applies to #262


**NOTE** This probably needs to be applied elsewhere too... Please EOL the namespace path routes @sizzlemctwizzle as the "conditional `?` doesn't work with an extra `/`
