This correction works fine for first MMI request, but there is another error 
for second MMI request.

After a AOT_CLOSE_MMI, if CAM wants to open another MMI, it will request to 
create an other RI_MMI (see logs below).

"ERROR: can't create session for resource identifier: 00400041"
"ERROR: unknown resource identifier: 00400041"

After AOT_CLOSE_MMI, RI_MMI should be destroyed.
I don't have yet EN 50221 specification.
