Request object was mocked but mocked value was never assigned.
In py2 moked object call is always successful. But in py3 if
value is not properly assigned it returns None. Causing the test
to fail. Removing the mocked object also fails the test so
removing it as broken test.

Added signal handler for COURSE_GRADE_NOW_PASSED to trigger single learner data transmission task in edx-enterprise.

Bumped edx-enterprise version to 1.10.7

Revert edx-enterprise version bump

DjangoTranslation object doesn't have ugettext attribute

Some of the tests are failing because DjangoTranslation object is
behaving differently with py2 and py3.With py2, it has 'ugettext'
attribute but with py3 it doesn't have.To make it compliant with
both versions modifications in the tests have been added so that
build will not fail.

reinstating commit cf78660ed35712f9bb7c112f70411179070d7382.
The original commit was reverted because I thought I found
bugs in it while verifying it on Stage, but it turns out that
it was simply misconfigured Stage data that causing errors.
