Make transaction manager global in JMSBridge
allow tests to set TM in TMLocatorImpl
Only Set TM on Bridge in QoS modes that require it

The bridge currently tries to assign a TM even when the quality of
service level is set to Duplicates OK.  This QoS does not use or require
a TM.  This patch stops the bridge from attempting to assign a TM for
this QoS and also checks that a TM is set of the other QoS.  If TM is
not set for a QoS that requires one, a error is logged and RunTime
exception thrown.
