What are the steps to reproduce this issue?

Have a method which accepts either 1 or 2 parameters by using an overload.

    local function returnTwoNumbers()
        return 1,2
    end

    ---@param _number1 number
    ---@param _number2 number
    ---@overload fun(_number1:number)
    local function acceptOneOrTwoNumbers(_number1, _number2)

    end

    acceptOneOrTwoNumbers(1, 2)
    acceptOneOrTwoNumbers(returnTwoNumbers())

What happens?

When passing 2 parameters manually there's no warning message, as expected.
However when using a function which returns 2 values, IntelliJ underlines the function call with the following warning: 0 results are excess arguments

What were you expecting to happen?

No warning to be given since its a valid function call.

Good timing, as far as bug reports go. I'm working on #58, so fundamentally making a bunch of changes to parameter handling. Planning on making another official release toward the end of the week.
