Error selecting from table: no such table: events

I'm using the latest image quiq/docker-registry-ui:latest and I run it with an /opt/data volume. When running ti is see this in the log:

Error selecting from table: no such table: events

I can see a registry_events.db file created in the data volume:

# ll
total 0
-rw-r--r--. 1 nfsnobody nfsnobody 0 May 25 14:31 registry_events.db

I see, there are no events yet and thus no table created.
I will fix so it does not complain in such cases.

The error is shown only once when sqlite db file is not yet created and it can be safely ignored.
I have improved this initial handling.
