fixed fish-shell/fish-shell#944

When the completion list includes the exact typed string with other
candidates, i.e. completion_t.match.type == fuzzy_match_exact,
the other candidates will be removed from the list, as they are not
the "best type". This is inconvenient for the user who wants to
type and complete commands in the other candidates.

The commit is to make the best_type to fuzzy_match_prefix as highest
priority, also, when comparing to best_type, the same or higher
priority completions can both match.
