Change-Id: I8444975637e859b161098310def6d2c6abda7127
ALLJOYN-2342 Fix Klocwork issue 1393 due to uninitialized variable
ALLJOYN-2361 Fix memory leak in DaemonSLAPTransport.
ALLJOYN-2043 Properly handle if the DBus Properties interface explicitly added.

We do not expect users to ever add the org.freedesktop.DBus.Properties explicitly however,
under specific situations the Java language bindings will add the Properties interface
explicitly.  This change will make sure the hasProperties flag is set when the properties
interface is explicitly added.
