Calling disconnect twice results in crash

[fabmazz]

I have a code that calls client.disconnect() when certain conditions are met.

However, I also want to disconnect when closing the fragment.

When I try to call client.disconnect() again, after the first one, the library crashes:

Process: it.reyboz.bustorino.debug, PID: 26148
java.lang.IllegalArgumentException: Invalid ClientHandle >wss://mapi.5t.torino.it:443/scre:mqtt-explorer-f173f581:it.reyboz.bustorino.debug<
