Don't allocate packet buf until connected #3

This goes in hand with https://github.com/adafruit/circuitpython/pull/2799. Don't allocate packet buffer until we're connected. At that time we know the MTU of the connection and therefore know how big the packet buffer can be.

While trying to use Stop() as a MIDI message, ran into one typo in the existing code and fixed it.
Add a one-second delay to the simpletest example. We need to wait for the connected device to start sending messages to us to have writes work properly. A 1-second delay was sufficient;0.5 seconds was not.
