Fix spurious binding loop errors in QtQuick Controls and other places

Commit 5dc7649f5ad7dca6e13707e827d001c3f118a6ef caused this regression,
as a result of lazy binding evaluation and self-referencing objects:

    import QtQml 2.0
    QtObject {
        property QtObject objectRef : subObject
        property QtObject blah: QtObject {
            id: subObject
            property int value: 42
            property int blah: objectRef.value
        }
    }

When blah is evaluated, we now lazily initialize objectRef - as opposed to
previously throwing an exception and then when objectRef gets initialized we
re-evaluate blah due to its dependency. So while evaluating "objectRef.value"
for blah, we initialize objectRef by evaluating "subObject", and after doing
that we write the "objectRef" property. That triggers a change notification,
and since the objectRef reference for blah is a compile-time known dependency,
the change notification triggers a re-evaluation of "blah", which is the
binding loop.

What's wrong here is that we register the pre-defined captures before the
code execution, when we should register them after the evaluation, or strictly
speaking after flushing pending bindings, like it is the case for individual
properties in bindings where we could not pre-determine the depenencies.
