Fix initialization order issue with DEBUG_ENABLED

Browse source 
If a user enabled Smack debug via the property 'smack.debugEnabled', a
ConnectionConfiguration could be created where debuggerEnabled is
'false', because Smack is not yet initialized.

Also make sure that if the property is not set, it won't overwrite
DEBUG_ENABLED = true.

Thanks to William Murphy for providing a detailed issue description and
supposing a fix.
