ALLJOYN-2023 Removed obsolete Doxygen tags from the doxygen config file.

Since removed flags are all using the default value they can be commented out
without affecting the doxygen build even if it is using an older version of doxygen.

ALLJOYN-2425 Removed check for uniquename from removesessionmember test

Since the session contains multiple members any of those members could have
triggered the session_member_added_flag.  Also a second member could be changing
the member_added_unique name while we are checking since multiple threads are
running at the same time.  This check was a verification check, and is unimportant
to the final result of the test so it has been removed to prevent false errors.
