daemon: properly disconnect signals, stop memleak

Whenever the daemon is polling on a device, a new signal is connected to
the object. This signal was not disconnected when polling stops which
resulted in a memory leak. Furthermore, whenever the "warning-level"
property is updated, the signal would result in an exponentially raising
call count (this happens when the battery percentage changes for
example).
