Fix flicker for AppDataUsage when zero usage

Browse Source 
When the page is entered from the AppInfoDashboardFragment, there is no
way to know whether the cycle data is available before finished the
async loading. If it's zero usage, the cycle spinner will be removed,
which cause a flicker.

Temporarily disable the preference list's animator before initial
page updates can solve this issue.

This also fix another flicker on this page when the background data is
off.
