Small fixes

[katy-sadowski]

Address #410 and #475 by allowing multiple CDM_SOURCE rows (and choosing a random one to populate the DQD metadata). A warning will be shown so users are aware of this.

Fix some small things in sqlOnly mode to enforce that "incremental mode" is only relevant when sqlOnly = TRUE.

Removes unnnecessary param in DB-to-JSON function.
