Title: keep persp-last persistent when using the with-perspecitve macro

This patch makes sure, that the variable `persp-last` is restored after the use of the macro `with-perspective` . This is very important, since I use `persp-last` a lot to jump between two perspectives. Now whenever a new perspective is created, the `with-perspective` macro is used and the content of the `persp-last` variable is useless, because it points to the currently active perspective.
After the patch this is fixed and `persp-last` is consistent over the use of `with-perspective`
