Activate REAP logic on all tables (Fix #11000)

Since REAP was not being properly passed down the
tree of GraphSteps, this commit considers any row
that is to be re-checked (i.e. is present in the
reapTableIds map) to be SOFT. In other words, a
failure for a row that will be processed again
later on does not constitute a hard failure.

Note: this is not necessarily strictly valid in
all cases. A row is in 2 separate subtrees, then
really it should be checked if the entire subtree
is to be re-checked. That logic may have to wait
for a revamp of the ome.services.graph package.

Tested via CMU-1 and openmicroscopy/bioformats#536
Disable the CHGRP-VALIDATION event logs

They don't represent an actual change to the data
and therefore serve little or not purpose.
