Subject: vim-patch:8.1.0149: session is wrong with multiple tabs when :lcd was
 used

Problem:    The generated sessions file does not restore tabs properly if :lcd
            was used in one of them.
Solution:   Create the tab pages before setting the directory. (Yee Cheng
            Chin, closes vim/vim#3152)
