Fix deferred execution

If the QML engine refuses to defer execution of a delegate (it contains
an ID), we must make sure to cancel any pending deferred execution for
the same delegate. Otherwise, we may end up overriding a custom (non-
deferred) delegate with a default (deferred) delegate.

This patch adds a new test style "identified" to tst_customization.
This style contains delegates with IDs so we can test the behavior with
IDs in base styles. Furthermore, overriding delegates is now tested
in various ways (with and without IDs in the base and custom styles) in
a separate test method. This is done by generating QML code to override
delegates with dummy Item instances with appropriate IDs and names.
