tabline: Give error message, if switching buffers is not possible
When using Neovim and switching to another buffer with the mouse and the
current buffer is modified, Vim refuses to switch buffers rightfully,
if the user has not set 'hidden' or 'autowrite' (because it is going to
unload the buffer from memory).

So catch this case and let the user know.

Note: :b! would be another possibility, but I do not prefer using this
attribute, because it is not clear what happens to the current buffer. I
think it is made hidden, but I prefer to be explicit here
