Apply the correct style to Battery and Storage page

Since some pages were styling the action bar programmatically before, the
color of collapsing toolbar will be overridden. Removing them will fix
the problem with inconsist color. This change also fixed some pages with
inconsist theme.

Bug: 185444608
Test: visual verified
1) Settings -> Battery / Storage
2) Scrolling the collapsing toolbar and make it collapsed
3) Observe and see if the color of toolbar is different from the one of
status bar
