PDB-341 Cleanup from review

* Cleanup :use blocks to use a list as is the convention
* Fixed v2 'not' queries to support the compile-not-v2 expression, not the v1
  version.
* Moved more items out of :use
* Created function for testing for a uuid response in testutils.clj and
  converted some tests to use it.
* Fixed assertion in v1/command.clj for time/parse
* Fixed some other assertions to use nil?, true? and false?
