This commit generates it all the time, without checking if we actually have any hints.

This is a possible alternative to haskell/vscode-haskell#168

But it may be better to update the CodeActionProvider interface to provide all the diagnostics for the given Uri/plugin combo, which can then be checked. Except that it may be too much processing, given the frequency of request.

This seems to be affecting stand alone hints? Just from looking at the diff it’s not obvious how exactly though

Some clients like coc.vim have keybindings to apply the first code action, so would it make sense to return this last?

Suggested change
return (catMaybes $ applyAll:actions)
return (catMaybes $ actions ++ [applyAll])
