Fixed the problem of Archived where while archiving any tour earlier it was showing us the COM_GUIDEDTOURS_N_ITEMS_ARCHIVED instead of showing us the string.
Worked on the Back Button (which was one of the main problems for Multi-Page functionality) of the Guided Tour Popper and made the Back Button functional for multi-page as well.
