Contact engine reset causes the ui to freeze for about 10 secs

[Renato Araujo Oliveira Filho]

During a reset signal from contact engine, the QContactsModel freezes for about 10s reloading all contacts.

HOW TO TEST
===========

1 - Make sure that you have about 1000 contacts on your list;
2 - Open Address book app
3 - Switch to a different app (make address book app go to sleep mode)
4 - Stop address-book-service
5 - Start address-book-service
6 - Wait about 5 secs
7 - Go back to address-book-app

Expected
========
Address book appear and is ready to use

Current
=======
Address book appears but in a freeze state and take a while to accept user interaction

Please test from https://launchpad.net/~ci-train-ppa-service/+archive/ubuntu/landing-009 and do the needed manual tests.

Also if possible, include a clearer test case when the problem is seen so that QA can easily verify the fix.

I am reviewing this in the wily queue. It looks fine but please make sure it is forwarded upstream so we don't have to maintain it forever and so that others can benefit.

[Timo Jyrinki (timo-jyrinki)]

I have asked Renato to commit it to upstream (he's a developer there), but so far it's not yet there: https://codereview.qt-project.org/#/q/project:qt/qtpim,n,z

[Renato Araujo Oliveira Filho (renatofilho)]

The upstream project has update the C++ API the patch will need to be very different. I still need to find some time to create a new patch that fits on the new API.
