Prevent an infinite loop when the trimmed text is shorter than the condensed length.
Prevent an infinite loop when the trimmed text is shorter than the condensed length.

When the contents of the element are only text (html.length == text.length) and the substring is as long as or longer than the condensed length (loc >= opts.condensedLength) and the trimmed body is shorter than the condensed length (clone.text().length < opts.condensedLength), then delta will be zero and the do/while loop will be stuck in an infinite loop.
