Fix for getting status of feature codes

Sign '#' was recognized as the end of feature code hence some of the
codes for getting status were not working, like:
*#43# - check status of call waiting
*#227# - check status of anonymous call rejection

The fix makes '#' not recognized as the end of feature code if the
previous character is '*'
