An Alfresco community upgrade from 4.2 to 5.1 fails over patch.fixWebscriptTemplate.

=== Failed to apply patch ===
update 5 april 2019,
This patch failure seems to be the result of the violation of a unique key constraint, namely: idx_alf_conturl_cr
Does anybody know how to work around this issue?
