Implicit transaction enabling during configuration fails

The implicit enabling of transaction support does not work in all cases described in TransactionMode Javadoc inside the current configuration API.

• transactionManagerLookup is explicit configured
  This works not in programmatic.

• enabled batching
  When using XML configuration, this will not work, when only <invocationBatching> element and no <transaction> element is used.
  At ConfigurationBuilderHolder.newConfigurationBuilder(...) the default cache config is used as base for the new named cache. Since build() is called, the TransactionConfiguration is set to NON_TRANSACTIONAL in the Configuration template used for the new ConfigurationBuilder. Later then any if(transactionMode == null)-related conditions in TransactionConfigurationBuilder will fail.
