Title: Websearch: fix for 'rhs is of unknown type'

* Fixes an error that was occurring when a new collection has been added
(and it had NULL in 'reclist' column of collection table). Because of
that, the intbitset in get_collection_reclist function was initialized with
None as a parameter and was throwing an exception.
