fix(quickfix list): avoid clobbering existing lists

[davidmh]

I've found a small issue with the quickfix list integration.

Setting the replace flag when sending grug-far results into the quickfix list truncates existing results. That's a problem because the quickfix list keeps a history of all the lists generated during the session, and you can navigate the history with :cprev and :cnext. Which means that populating the list from grug overtakes whatever list is currently displaying.

For example, imagine you have the lists in :chistory

	order	title
	1	LSP references
	2	Some other plugin list
*	3	LSP references

Then you navigate back to see the second list with :cprev.

	order	title
	1	LSP references
*	2	Some other plugin list
	3	LSP references

Then you use grug-far and send the results to the list:

	order	title
	1	LSP references
*	2	Grug FAR results for: someString
	3	LSP references

Now I've lost Some other plugin list.

Inserting a brand new entry seems like the desired behavior, not only prevents clobbering existing lists, but also helps you navigate previous grug-far results without opening the grug-far ui first.

I assume you meant :colder instead of :cprev but good catch in any case. Thank you for the fix! Much appreciate! 😄

Yeah, you're right, I went by (faulty) memory as I have already mapped those commands to < and > in the quickfix buffer 😅
