* (bug 27761) Fix regression: pages with Esperanto titles containing convertible character sequences became unreachable

Fixes regression from r70871 -- a comparison originally made against the raw GET 'title' variable was changed to use WebRequest::getText() instead, which performs character conversion. This caused infinite redirect loops for titles containing convertible forms such as "ux", which in a recodable field would be round-tripped via "uxx".
This fix changes the comparison to use WebRequest::getVal(), restoring the original direct comparison and avoiding the redirect loops.

(Another nice reminder that this old system with the pseudo charset conversion is obsolete -- it should be replaced with a more modern browser-based input conversion that can apply to all text input fields.)
