R: Autocompletion appends parentheses when there are already parentheses

[FinYang]

Currently in Positron, when typing function in front of parentheses, accepting autocompletion will add another extra parentheses.

This isn't consistent with RStudio, where no additional parentheses are added.

This is an issue for me because I am used to sometimes type the parentheses first then the function name, for example when I want to change the function, or add another layer outside without using pipe.

I was sure we already had an issue for this, but I can't find it! Let's track this here then (it's been on our minds too).

Related to #2338 in that it is about adding parentheses when we don't want any.
