Previously the QContactManager would lazily connect to the engine signals when the manager was connected to, but unfortunately the V2 engine wrapper itself was always connecting to the wrappee's signals. So V2 engines got lazy signals, but V1 engines (most of them) did not. So now tweak the signal connection code a bit to take advantage of the simple signal proxying that the wrapper used to do. This might need refactoring in the future if a V3 wrapper emits signals itselfs, though. Change-Id: Id75e40a8da09133a53cef9ce18ec0d5e430e7fbc Task-number: QTMOBILITY-507 Reviewed-by: Chris Adams
