We have covered the same test in the new test file. See "CREATE
SUBSCRIPTION sub CONNECTION '$publisher_connstr' PUBLICATION pub WITH
(disable_on_error = true, ...". This will test the cases we were
earlier testing via 'disable_on_error'.

The reason to keep the name 'on_error' is that it has tests for both
'disable_on_error' option and 'skip_lsn'. The other option could be
'on_error_action' or something like that. Now, does this make sense to
you?
