Link dialog code is outdated after JS links has been forbidden

[Piotrek Koszuliński]

Since #9289 JS links aren't allowed, but I found some evidences that that patch wasn't complete. E.g.:

urlOnChangeTestOther = /^((javascript:)|[#\/\.\?])/i;

Few lines later part of this pattern is invalidated:

if ( (/javascript\:/).test( this.getValue() ) ) {
    alert( commonLang.invalidValue );
    return false;
}

Taking into consideration comment 10 from #9661 and comment 8 from #9637, I'm closing this issue as invalid.
