Fix :)

Everything in order, gl front end :) @Joris + @Lorenzo

If there is an error retrieving the database info an error is now
returned.

Most of this code was taken straight from the schema service. No tests
were written because this is entirely dependent on external
dependencies.

An error message now gets published if there is an error while
converting the query or there is a database error.

Updated integration test

Also updated Makefile and deployment file.
