Properly fail when creating XapianSearcher on a zim without embedded index. 

The XapianSearcher creation must fail with a exception if we cannot open
the xapian database.
So, if we try to open a zim and there is no embedded index, we must fail.

We raise the custom exception NoXapianIndexInZim in this case.
