fix(lsp): ensure pending changes are flushed on skipped debounce (#17015)

Browse Source 
Follow up to https://github.com/neovim/neovim/pull/16881

Document changes could get sent out of order to the server:

    1. on_lines: debounce > 0; add to pending changes; setup timer
    2. on_lines: debounce = 0; send new changes immediately
    3. timer triggers, sending changes from 1.
