o In start/2 and stop/1, the IQ registration must use a namespace as

atom, not list.
o  The functions process_local_iq/3, process_sm_iq/3 and get_last/3
receive an #iq, not an #xmlel.
o  In store_last_info/4 and remove_user/2, add try/catch block around
exmpp_stringprep:*prep/1 uses.

defaults to the atom "undefined", not an empty binary. Fix a bug where
we expected an #xmlelement to have only one #xmlcdata child.
* src/mod_last_odbc.erl (start/2, stop/1): The IQ registration must
use a namespace as atom, not list.
(process_local_iq/3, process_sm_iq/3, get_last/3): These functions
receive an #iq, not an #xmlel.

exmpp_stringprep:*prep/1 uses.
