Fix XmppConnFactoryBeanTests config for parser

The `xmppDomain` has two setters on the `XMPPTCPConnectionConfiguration.Builder`,
so the Java Bean specification may choose a wrong one by name and the
provided value may not fit into expectations

* Rework `XmppConnectionFactoryBeanTests-context.xml` to avoid ambiguity
with target setters presence
