[performance] improve app startup time

Fixing this bug https://bugs.launchpad.net/ubuntu-ui-toolkit/+bug/1346975, should help on the app performance.

in address book make sure the component that fetches frequently called numbers does that on demand and not when component is instantiated, as well as general profiling of the app startup.

  [ Olivier Tilloy ]
  * Reduce startup time of both apps by means of a few tricks, all
    related to asynchronous loading: - ensure loaders on the critical
    path load their components asynchronously - instantiate the error
    sheets asynchronously, as they are not needed right away - use
    Component.incubateObject(…) instead of Component.createObject(…) to
    instantiate objects asynchronously where possible - instantiate the
    history and bookmarks models asynchronously (LP: #1325001)
