Problem: When 'hidden' is set session creates extra buffers.
Solution: Move :badd commands to the end. (Jason Franklin)

Adjust some tests in ex_cmds/mksession_spec.lua:
- 'restores same :terminal buf in splits': Buffers aren't always :badded
in the same order as they're :edited, :balted, etc, so the order of
buffers in the buffer list may change slightly now that :badd happens
afterwards.
- 'restores buffers with tab-local CWD': This is explained in a comment.
