bitbake: hob/packageselectionpage: Correctly restore previously selected packages

"Back" button from "Packageselection" page now restores correctly previously
selected packages list. Till now "Back" button was implemented just to switch
pages, not to cancel changes you have made to packages list.

[YOCTO #2984]
