QQmlDelegateModel: Avoid allocating unnecessarily
Wait for the update request to be posted and take effect before piling another
one up.
This speeds up qmlbench creation benchmarks a bit (as they make use of Repeater).
Results for benchmark/creation/delegates_item on a 5.6 base on a 2011 mbp:
Before: Average: 670.4 ops/frame; using 5/5 samples; MedianAll=674; StdDev=6.34, CoV=0.00946 - StdDev (all samples included)=6.34
After: Average: 702 ops/frame; using 5/5 samples; MedianAll=700; StdDev=8.97, CoV=0.0128 - StdDev (all samples included)=8.97
