Updated the createEntity method on tests to be public so that it is accessible by other tests.  This is a change that has been reflected in all other test classes.
Added javatuples and joda-time dependencies.
Fixed a performance bug in the findAll method where the count was calculated twice.
Merge branch 'develop' of github.com:OpenHMIS/openmrs-module-openhmis.commons into develop
Changed the test base class back to BaseModuleContextSensitiveTest because using the Web base test class was causing issues in the cashier tests (and possibly others).
