toggle_instance should not fail then buffer with that instance is deleted.

I'm trying to configure nice persistent config, mostly using named instances.

Steps to reproduce:

1. Open any file buffer.
2. Swan named buffer with grug-far: :lua require("grug-far").toggle_instance({ instanceName = "far", staticTitle = "Find and Replace" })
3. Delete buffer: :bd
4. Spawn same buffer: :lua require("grug-far").toggle_instance({ instanceName = "far", staticTitle = "Find and Replace" })

Expected behaviour: When named buffer not found, new one is created.

Actual behaviour: Error:

E5108: Error executing lua ...34/.local/share/nvim/lazy/grug-far.nvim/lua/grug-far.lua:310: Invalid window id: 1013
stack traceback:

@choovick thanks for the clear bug report! Problem should be fixed now 😄 Closing the ticket for issue management purposes, but feel free to re-open if you run into any problems.

@MagicDuck thank you for a quick fix! Can confirm new empty instances are spawning post buffer deletion of grug-far!

Thank you so much for mazing plugin 🎉 final piece for me to just the ship from Intellij and VSCode.
