djvu.py: Fix parsing and page deletion checks

If only one page is present, _get_page_info() was swapping the key, id pair: - key, id = '', 1 needs to be swapped.

Checks after page deletion need to be fixed when file is left with one page only: - assertion needs to consider that key = '' - number of pages before deletion n_tot is > 2 if files have more than one page after deletion.
