Jira791 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 CommunitySketches/StandardFirmataBLE/BLEStream.h.
    Move the add profile at begin after HW complete initial process.
