Removed assertions in setUp and tearDown. Fixed files to removing
warnings in them. Added a delete collection in the Restore database
because when it creates an index it is also creating a collection (and
then the Drop database test is failing because it finds the collection
there). 

Also, order in restore bean in AutomationSpringBeans to be
#{T(org.mule.module.mongo.api.IndexOrder).ASC} because of previously how
it was, it used to give class cast exception IF the test was actually
executed (but it was @Ignore so that error was never being caught).
