Bug 28462: Remove TT tag on several lines - opac-advsearch.tt

It fixes the translation in case the operators have been translated

Test plan:
1. misc/translator/translate update pt-BR
2. In pt-BR-opac-bootstrap.po , find OpacAdvSearchMoreOptions
3. sabotage the translation part, like replacing IF with something else
4. misc/translator/translate install pt-BR
5. enable and use pt-BR and hit opac-advsearch.pl
6. Notice the error
   Template process failed: file error - parse error - /kohadevbox/koha/koha-tmpl/opac-tmpl/bootstrap/pt-BR/modules/opac-advsearch.tt line 409: unexpected token (e)                                                    [% IF (OpacAdvSearchMoreOptions and OpacAdvSearchMoreOptions.size> 0 e extended_options) ou (OpacAdvSearchOptions and OpacAdvSearchOptions.size> 0 e n expandido_options) %] at /kohadevbox/koha/C4/Templates.pm
7. Apply the patch and redo update and install of the language
8. Note that it's now working
