Prevent import-examples to fail

The mariadb images seems to now allow a smaller maximum packet by
default. This resulted in problems for the boolfind problem which we
didn't detect as all checks would still pass correctly.

We now also capture the SQL logs to detect this easier and increase the maximum packetsize (1G).
