Continue animations started from AppWindowToken.

Animations that were started from AppWindowToken.showAllWindowsLocked
were not setting mInnerFields.mAnimating and hence the animations were
not progressing. This resulted in popups such as menus and time/date
settings not showing up.

Fixes bug 6205076.
