MST-1317. The enrollment mode of a learner should still display on the course listing, even if IDV is disabled. Right now, all enrollment messaging is disabled if IDV is turned off, as we are no longer returning the verifications status for a learner in that case. We should still return the enrollment mode if IDV is disabled, but exclude any IDV messaging.
In the PR https://github.com/edx/edx-platform/pull/10659 the outer_atomic decorator/context manager was created to prevent nested atomic blocks. This method received a boolean parameter read_committed to enforce read-committed MySQL isolation level. From Django 2, the default isolation level Django sets is read-committed, so the aforementioned parameter for outer_atomic can be removed
