revert: persp-mode

Bad-ptr/persp-mode.el@82680795b3 -> Bad-ptr/persp-mode.el@40e9993a97

persp-mode introduced some breaking API changes in a recent refactoring,
which have caused issues that are difficult to opt out of, even by
repinning it to an older commit. Until persp-mode sorts things out, I
simply revert it back to a point before all the changes.
