Code review comment for lp:~diegosarmentero/ubuntuone-client/ubuntuone-client-publishapi

We needed to store a list of handlers to be called, because the setattr is overriding the behaviour of that part of the object every time a connect_signal is requested, and it was happening that several functions were being connected to the same signals, the ones with the handler that we actually want, and some other for clean up at syncdaemon core, and only the last handler connected was the one that was being called.
