Remove some special casing

This special casing is useless. If the word is the same as what
user typed, the scoring algorithm already ensures that it comes
out at the top. Actually, as is written in a comment here, code
executed later is actively relying on this suggestion having
the top score ! There is no need to test it for equalness and
inserting it at the top then.
