--accept-nth ignored with --filter

[dicktyr]

--accept-nth has no effect when used in combination with --filter

the --query option respects --accept-nth

% echo 'one two three' | fzf -d ' ' --with-nth 1 --accept-nth -1 -q one
three

but --filter does not

% echo 'one two three' | fzf -d ' ' --with-nth 1 --accept-nth -1 -f one
one two three
