(#178) - No more crash when ';'-ending view function
(#182) - use pouchdb-extend
(#195) - fix coverage

Apparently istanbul got smarter at some point and caught that
in create-view.js at the line:

    view.seq = lastSeqDoc ? lastSeqDoc.seq : 0;

The first condition was never occurring, due to the caching.
Closing the database and opening another one susses this out.
