[cros-fuzzy-app] Remove unnecessary check.

Doing some cleanup as part of search consolidation.

FuzzyTokenizedStringMatch::IsRelevant already checks case-insensitve
matches between query & text:
https://cs.chromium.org/chromium/src/chrome/common/string_matching/fuzzy_tokenized_string_match.cc?g=0&l=278-287

Hence we don't need to repeat the check. Note
(i). |query_terms| is tokenized string of |query_|.
(ii). |indexed_name| is tokenized string of |app->name()|.
