The whole point of keeping the meter connection in a hash of its own was that not a line of the generic and solarEdge vendors would change. Checks it rather than claiming it: a stored solarEdge connection, whose behaviour no suite covered until now, must still end up with exactly one connection, as must a generic one. Also records the connection a discovery came from in processDiscoveryResult() rather than in the discoveryFinished handler. The initial setup calls it from a second handler on the same signal, so recording it there made the orphan sweep depend on the order Qt happens to invoke the two.
