[BUGFIX] Shows error for empty filenames (vim-startify)

Browse Source 
There was a fix in #1043 which improves the behavior for non saved
filenames. Those are not on disk, but also not empty. This lead to an
issue #1059 where actual "empty files" like created with vim-startify or
stdin lead to an error. This change fixes this by adapting the order of
the tests. It'll print "no file for the current buffer" for empty files.

Solves #1059
