QmlDesigner: fix regression uncovered by tests

Fixing a regression in the meta info system.

We follow now Qthe Declarative1StateOperation convention (note the 1).
Since this data is provided by Qt Creator it is independent from any Qt
version. (4.8/5.1)

Also the type comparison was broken in NodeMetaInfo for <cpp> types.
PackageName() does retrieve the package name of the cpp type which might
be different from the one used in qualfiedTypeName().
