Fix string comparison for .Truncated page variable

Instead of `strings.TrimSpace()`, use `strings.Join(strings.Fields(s), " ")`
to collapse all whitespaces into single spaces, in order to match the
behaviour of helpers.TruncateWordsToWholeSentence(),
in order to detect non-truncated content correctly.
