Remove $VERBOSE = nil from tasks.rb

Permanently setting $VERBOSE to nil causes unwanted side effects (warnings generated by app code are
silenced when triggered by a rake task but visible otherwise). silence_warnings {} would be safer to
use here since it resets $VERBOSE back to what it was when the block finishes.
Refactor `ArrayParser`

* Constantize parse token
* Remove extra param passed to `parse_data`
assert_no_queries should allow to ignore some queries
assert_no_queries should ignore certain sqls

postgresql test if randomly executed then executes "SHOW max_identifier_length". Hence
the need to ignore certain predefined sqls that deal with system calls.
Rails.logger should have level specified by config.log_level. 

Fix bug when log level of Rails.logger (which was set via config.logger) does not match the    config.log_level.

Remove duplication from date_time calculations

Methods: :past? and :future? are already defined identically
in date_and_time/calculations.rb which is included in Date.
Because DateTime is a subclass of Date, it can call them.
