task: make setting service handle conflict on insert (#9160)

Currently, in enterprise we're struggling with setting service and
transactionality; all our verfications says that the setting key is not
present, so setting-store happily tries to insert a new row with a new
PK. However, somehow at the same time, the key already exists. This
commit adds conflict handling to the insertNewRow.
