Sketch crash using both Firmata and BLE library, gitHub issue #377

1. The BLEStream object adds profile when boot but the HW doesn't be
    initialized and makes APP crash.
2. Change the BLE initial process not depend on HW. Buffer the
    attributes if HW not initialized.
3. Changed files
    libraries/CurieBLE/src/BLEDevice.h - expose constructor
    libraries/CurieBLE/src/BLEPeripheral.cpp - not call HW init function
    libraries/CurieBLE/src/internal/BLEDeviceManager.cpp - change init order
    libraries/CurieBLE/src/internal/BLEProfileManager.cpp - change constructor
