[PATCH 0/3] Add null text/alpha identifier and icon check handling

Hi, Following patch adds the missing "text/alpha identifier and icon" check handling. As per the ETSI 102 223 section 6.8, Text string is only required in response to a GetInkey or GetInput proactive command. So, there is no need to add any specific handling for null or empty strings cases. As per the ETSI TS 102 223 section 6.5.4, "If the terminal receives an icon, and either an empty or no alpha identifier/text string is given by the UICC, than the terminal shall reject the command with general" result "Command data not understood by terminal"."
