Update SmsReceive: Deal with fixed number addition random number context

[hongnod]

Some SMS number will append random number on a fixed number, so save the fixed part ,if fixed part matches, process the transition.

it can break existing functionality: consider you have 2 sms templates for 900 tel number and for 9001 - then the 9001 one can never be selected and 900 will be always triggered instead.

Yes, that case has such problem. but in reality, we don't have such kind of number.if actually has, define 9001 template as another 900 is enough.
