clean up I2C pin handling in audioreactive (ES7243+ES8388)

* remove double Wire.begin() - Wire cannot be re-initialized; its already started by pinManager.joinWire()
* Only use global I2C pins; make sure that audireactive I2C settings are aligned with global I2C pins
* minor cleanup
* remove I2C pins from AudioSource::initialize()

Note to self: sdaPin, sclPin are just dummy values now, good for UI consistency, but unused otherwise. Could be removed.
