Title: Makes clear three transactions application modes

Internal, external and recovery. This means that we no longer "piggy back"
on recovery mode for external transactions being applied in HA.

This distinction exposed a problem where we evicted nodes unnecessarily
when deleting relationships, even in internal application mode. Another
problem with patching relationship chain caches was exposed and fixed.
