Replace isset() with null check in SimpleCaptcha

Browse source 
Found usage of isset() on expression $this->captchaSolved that appears
to be always set. isset() should only be used to suppress errors. Check
whether the expression is null instead.
See https://www.mediawiki.org/wiki/Manual:Coding_conventions/PHP#isset
