Bug Description

The split for discussions cannot be created when there are no discussions/notes.

Reproduction Steps

1. Check out the feature branch for which no discussions exist in the MR
2. Open Neovim
3. Run :lua require("gitlab").review()
4. You will get the following error:

Fixed in develop by #273 and #275, if not let me know here with another comment. Thanks for pointing this out, there were some refresh issues with empty state.
