GET params get duplicated if no locale is provided
Hey,

not sure if this is an `ladjs/i18n` issue I just took a brief look at the redirect implementation.
But if you goto: [https://lad.sh?test=test?test=test?test=test%3Ftest%3Dtest](https://lad.sh?test=test?test=test?test=test%3Ftest%3Dtest)
you can see it.
