Don't sort CodeActions

Returned code actions are often sorted in a predetermined, preferred
order. For instance, when proposing actions to handle error propagation
on a throwing function the option to handle the error with `try` should
appear before the more dangerous option to disable error propagation
with `try!`.

Fixes #1696
