A big shoutout to @simonmclean for this pull request. Previously we autoloaded a session file as soon as Neovim opened. The problem with this is that key plugins like LSP and Treesitter may not have been initialised. This would lead to syntax highlighting issues or LSPs not attaching to buffers in the session. Pushing this to Neovim's event loop via vim.schedule allows us to sensibly load the session after these key plugins. Fixing the tests was a little cumbersome as we needed to use plenary's async library but once figured out, we have some lovely robust async tests
