Bug 35676: Fix DidYouMean when not configured

When DidYouMean is not configured, there is the following message
displayed:
  "Not what you expected? Check for suggestions"
suggestions is a link to svc/suggestion which does not return content if
the feature is displayed
 90 unless ( @plugins ) {
 91     print $query->header;
 92     exit;
 93 }

We should not see this text, it is supposed to be replaced when the ft
is enabled.

However
  commit 79bf4485c1b2ae8059e2ee15ea1e67bba9961c34
  Bug 34866: Use template wrapper for breadcrumbs: OPAC part 4
made this change:
-                    [% IF ( DidYouMean ) %]
+                    [% #IF ( DidYouMean ) %]
                         <div id="didyoumean">Not what you expected? Check for <a href="/cgi-bin/koha/svc/suggestion?render=standalone&amp;q=[% querystring | uri %]">suggestions</a></div>
-                    [% END %]
+                    [% #END %]

Which is obviously wrong.

Test plan:
Do not have the ft configured and launch a search (OPAC) that will not
return any results.
=> Without this patch there is the message
=> With this patch applied it is no longer displayed
