Revert "[persistence] [api] Change default caching behavior in couchdb adapter to false"

This reverts commit 2ed6901d2a60ef1ce63d92b5419b0382e71a730b.
Caching is bad when multiple services are modifying the same
couchdb, but the cradle jugglingdb adapter generally assumes
that caching is on.
[jugglingdb] [fix] Check for existence of design doc before creating
[api] Remove the "where" clause from calls to .find method
[test] persistence test now depends on non-caching behavior in couchdb
[jugglingdb] [minor] Code reorganization in cradle adapter dynamic view creation
