30677	Improve Exception Message In Test Client and urlencode() when None is passed as data.	Keith Gray	Swatantra	"I am upgrading to 2.2.1 from 2.0.5 and my tests are failing due to a change in the test client: https://docs.djangoproject.com/en/2.2/releases/2.2/#miscellaneous. It now throws an exception if a None value is provided in data given to a POST. I would like to propose an improvement to the message to display the offending Key and Value that generate the exception.

I have a proposed change in my fork on github: https://github.com/idahogray/django/tree/ticket_30677"	Cleanup/optimization	closed	Testing framework	dev	Normal	fixed	test client post		Ready for checkin	1	0	0	0	1	0
