Jira791 Sketch crash using both Firmata and BLE library, gitHub issue arduino#377

1. The BLEStream add profile when boot but the HW doesn't be initialized and
    makes APP crash.
2. Change CommunitySketches/StandardFirmataBLE/BLEStream.h.
    Move the add profile at begin after HW complete initial process.
