justify: verify being in a paragraph before trying to find its beginning

If find_paragraph() detects that we're not in a paragraph, it moves
forward a paragraph and then backward to that paragraph's beginning.
Make it check whether we're in a paragraph before moving backward
(since there might not *be* any more paragraphs), to prevent going
forth-and-back and never reaching the end of the buffer.

This fixes https://savannah.gnu.org/bugs/?54573.
