gpioserver spi bus shutdown fails #220

The spi bus #shutDown method is using the wrong key in the allocated bus' dictionary.

timrowledge commented 8 years ago

The problem was that the SPIBus version of #release - used when closing down the use of spi - was sending super release, which was erroneously implemented as AllocatedSPIBuses removeKey: self.

By removing the super send and indeed replacing the superclass version with a subclassResponsibility send we avoid the entire problem.
