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.

A GEN24 answers for the inverter on unit ID 1 and for its Smart Meter on
unit ID 200 by default, behind the same host and port. One thing now
carries two SunSpecConnection objects, the second one driven by the
meterSlaveId parameter that until now no line of C++ ever read.
The meter connection is created during setup but left idle: it is only
brought up once the primary connection has finished discovering, so the
two never handshake at the same time towards the same inverter. An
absent meter never fails the pairing, since a GEN24 without a Smart
Meter is a legitimate installation and the parameter has a non zero
default the user did not choose.
thingRemoved() and the reconfigure path now dispose of both connections
through a single entry point. Their else if chain used to stop at the
primary one, which left the meter connection outliving its thing with an
open socket and signals pointing at a destroyed Thing.
Child things look their model up across every connection of their
parent. The two connections of a GEN24 never announce the same model ID,
so no discriminator has to be persisted.
Adds a test suite instantiating the plugin behind a real ThingManager
with two connections. It lives in its own binary because the F1 suite
checks global call counters that extra configured things would falsify.
