Eval: do not join a list if it's empty anyway #2441
This spares some work and also prevents list_join() from calling ga_init()
with a growsize of 0 which would lead to the nvimlog being littered with:
[warning @ ga_set_growsize:64] 17675 - trying to set an invalid ga_growsize: 0
Also in Vim 7.4.702
