Comments in empty functions are moved next to function parentheses

[ok-nick]

Before format:

local function foo()
	-- bar
end

After format once:

local function foo() 	-- bar
end

After format twice:

local function foo() -- bar end

Since this is a syntax breaking bug, for the time being I would recommend adding -- stylua: ignore above the function definition to unblock you
