Aleix Pol bb2688392a Reduce many connect() warnings when loading Declarative plasmoids.
Right now, every QML plasmoid can provide a number of properties
(6, actually) to specify some size hints (maximum, minimum and
preferred).
If you don't provide those properties you get many warnings because
of the missing changed connections. This patch removes such warnings
by making sure the property is present before connecting and querying
the property at all.
