using mariadb jdbc driver in compose setup causes database to not be traced

[driesdeproost]

using

jdbc-driver:
    image: xeniteu/jdbc-mariadb:2.2.5
    volumes:
    - jdbc:/jdbc/

from jdbc-drivers in integration-tests/src/integration-test/resources/compose/docker-compose-mariadb.yml causes the db to not be traced in zipkin.
Alfresco works as normal though, so the db requests must be passing through the used P6SpyDriver.

This bug does not happen if you use xeniteu/jdbc-mysql:5.1.42 or a PG setup.
