Improve portability between different versions of Arduino-ESP32. 

The BLECharacteristic::getValue() method returns std::string in
older versions of Arduino core for the ESP32 and String in newer
versions.

However, the return value is used in a way that both classes support:
using only length() and c_str() methods.

Hence, replacing explicit type name with auto keyword makes the code
compatible with older and newer versions.
