app.py: Fix Solr queries for item views

Browse Source 
According to dspace-api's Constants.java, items are type 2 and they
use a unique ID field of `id` instead of `owningItem`. There is no
need to check the bundleName for item types.

Also, I decided to use the main Solr query for item IDs because the
filter query parameter (fq) stores results in the filterCache and
can be quite expensive with cores storing tens of millions of docu-
ments (we currently have 149 million docs!). It makes sense to use
the filter query parameter to reduce the result set returned by the
main Solr query.
