Only check force_collect in collect_tokens_trailing_token.

Browse Source 
There are three places where we currently check `force_collect` and call
`collect_tokens_no_attrs` for `ForceCollect::Yes` and a vanilla parsing
function for `ForceCollect::No`.

But we can instead just pass in `force_collect` and let
`collect_tokens_trailing_token` do the appropriate thing.
