Don't show titles in the tabline if there aren't any

Browse Source 
airline#extensions#tabline#buflist#list doesn't pick up some buffers
(most notably Netrw buffers), so there are sometimes no buffers to show
and the tabline code fails with an error. This avoids that situation.

It would be better to detect these and show titles for them, but for now
this restores the old behaviour.
