patch 8.1.0149: session is wrong with multiple tabs when :lcd was usedv8.1.0149

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 #3152)
