Exclude arquillian-transaction-jta for tomee.
Openejb have an own TransactionProvider.
In this commit i exclude it in test pom, and introduce as a new dependency in every other test profile.

Exception fixed:
java.lang.IllegalStateException: Multiple service implementations found for interface org.jboss.arquillian.transaction.spi.provider.TransactionProvider. org.jboss.arquillian.transaction.jta.provider.JtaTransactionProvider, org.apache.openejb.arquillian.transaction.OpenEJBTransactionProvider
	at org.jboss.arquillian.core.impl.loadable.ServiceRegistryLoader.onlyOne(ServiceRegistryLoader.java:74)
	at org.jboss.arquillian.transaction.impl.lifecycle.TransactionHandler.getTransactionProvider(TransactionHandler.java:243)
change drop table order in create.sql
This way foreign key constraints not violated.
opnejpa sequence table is not 'sequence'
it is 'openjpa_sequence_table'
A hack for tomee-openjpa lazy initialization
It seems openjpa generates the schema too late.
Schema created at fist EnityManager usage, potentially _after_ datasets, or scripts.

This bug affects more test classes where persistence-test.xml used.
