Fix EZP-22353: Travis database error on ezpublish-community

Link: https://jira.ez.no/browse/EZP-22353

## Description
Since Refactoring of Legacy SE to use Doctrine DBAL https://jira.ez.no/browse/EZP-22151 the travis would fail on ezpublish-community because database parameters needed to be mapped in a different way.

This is a temporary fix until the followup story is done https://jira.ez.no/browse/EZP-22279

## Test
I added a temporary commit on my ezpublish community PR to have composer.json pointing to this branch for ezpublish-kernel, and now test are passing: https://github.com/ezsystems/ezpublish-community/pull/106
