Fix registering the QIviPendingReplies at startup

Using a singleShot timer is not the right way as it doesn't make
sure the call is really executed in the next event loop run.
Instead use QMetaObject::invokeMethod().

Also reorder the qivipendingreply autotest to make sure the QML
test is done first, which needs the types to be registered...
