Container based on xwiki:lts-postgres-tomcat does not start reliable

Unfortunately this did not work.

Trying now this:
https://jira.xwiki.org/browse/XWIKI-18436?focusedId=108620&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-108620

from here

Will see if this works.
