* lisp/emacs-lisp/package.el (package-isolate): Use `package-activate-all`

`package-initialize` is used to initialize the whole machinery needed
to list/download/install/remove packages, whereas here we only need to use
the installed packages.

(cherry picked from commit ff87166227b2634e45591e8c73db9b102734ab77)
