Can't deploy with already existing tables (user made)

[snaeil]

Concerto Platform version

5.0.20

Expected behavior

Deploy a database before Concerto, keeping User made tables in it already.
These tables have to be accessible from within Concerto.

Actual behavior

Having the User made table in the database already leads to an incomplete deployment without Concerto being started,

Complete docker log for Concerto:

Steps to reproduce the issue

1. Create the table before has it
2. Deploy Concerto using CONCERTO_CONTENT_URL so that Concerto will try to use the tables defined in export.concerto.yml.
3. Find yourself stuck with the same log as you can see above
