Issue #420: Avoid supervisor crash without connection by properly memoizing promise-returning functions

Browse Source 
device.getID caused a fatal error when connection was down, as the memoization with `promise: true` throws
synchronously. Changing memoizee to use `promise: 'then'` makes the memoization work as expected.
