This changes `formatMatches` to notify the user that they can
select the single result. This is a more clear result compared to
the previous one.
This closes the following issue: https://github.com/ivaynberg/select2/issues/2329
This change syncs the translation template with the actual string
used for `$.fn.select2.defaults.formatInputTooLong`.
