fix(lsp): avoid scheduling client deletion before LspNotify #37685

Browse Source 
Problem:
`Client.on_exit` runs `Client._on_detach` and the client removal logic
within two separate `vim.schedule` sequentially. However, since
`Client._on_detach` executes `LspNotify` inside `vim.schedule`, this
causes `LspNotify` to be executed after the client removal, which is
scheduled first. At that point, a valid `Client` can no longer be
retrieved within the autocmd callback.

Solution:
Put the client deletion inside the `vim.schedule` call.
