How to reproduce the problem

nvim starts with error after this PR #958. It was working fine without errors before that. It appears that refresh() method is now throwing an error. The reason refresh() is called it is to avoid unwanted flashing in the tabline.

Expected behaviour

Start neovim without error

Actual behaviour

Receiving the following error when starting neovim

This issue also happened to me, and I had to search any string using / to fix it.

Example: /test

After searching, I restarted Neovim and now the error is not thrown. When running on a new Neovim installation, vim.fn.searchcount() returns a vim.empty_dict().

Nice, Thanks! I confirm it works now as expected after the update.
