drop-script-source set for h2 test after bumping to 2.2.220 version is not working properly for jbpm-container tests:

WARN [org.hibernate.tool.schema.internal.exec.ScriptSourceInputFromFile] (ServerService Thread Pool – 99) Specified schema generation script file [drop-tables.sql] did not exist for reading

It must have an absolut path to be read correctly.
Also it's needed to add these 2 properties to the other persistence.xml file for the rest of jbpm-container-test-suite
