Mms: fix CRASH when the address contains only spaces

Rootcause: If the address contains spaces only,when Mms
format this address,it will get an address string the length
of which is -1. So crash happen when call span(object,0,-1,flag)
function.

Solution: When user press back key to restore the message.
This patch will check the address is valite or not, if it is
invalite,it show a dialog to tell user he can't restore the message.
So it avoid crashing when enter the message again.
