#1185 Match case works in reverse

[Mario Valle]

In my project I have the bibliographic key "Steen1988" present in the bib file and in one \cite{Steen1988} call.
Searching in files with no "Match case" toggled on the string steen1988 results in nothing found. If I search for Steen1988 the reference and the entry in bib file are found. But with "Match case" toggled on the lowercase string matches the uppercase one in file.

Fixed.
