TerminalPanel: Disconnect destroyed signal in destructor

Otherwise, when QObject cleanup, which runs after our destructor,
destroys the terminalPart, it would call back into us
when we're already half-destroyed.

This trips an assert in Qt "Called object is not of the correct
type (class destructor may have already run)"
