1. fix(lsp): ignore hover and signatureHelp responses on buffer change …

   Language servers can take some time to respond to the
   `textDocument/hover` and `textDocument/signatureHelp` messages. During
   that time, the user could have already moved to another buffer. The
   popup was always shown in the current buffer, which could be a different
   one than the buffer for which the request was sent.
   
   This was particularly annoying when moving to a buffer with a `BufLeave`
   autocmd, as that autocmd was triggered when the hover popup was shown
   for the original buffer.
   
   Ignoring the response from these 2 messages if they are for a buffer
   that is not the current one leads to less noise. The popup will only be
   shown for the buffer for which it was requested.
   
   A more robust solution could involve cancelling the hover/signatureHelp
   request if the buffer changes so the language server can free its
   resources. It could be implemented in the future.
