[427017] Revert previous changes for this ticket

Tests show that we do not understand the impacts of removing the
AirDCrossReferenceAdapter well enough yet. With Luna M7 approaching
there is too much risk in introducing regressions; we'll try again after
M7 is released.

Fix potential NPE when trying to reload a session

In some circumstances which probably depend on timing/threading issues,

session which has already been closed, in which case the
DAnalysisRefresher needed for the reload may be null.
