Apply correct styles to account filter activities on tablets

We use dialtacts_theme_color defined in ContactsCommon to ensure that
both Contacts and Dialer work well.

In addition, ag/808228 checked the "Customize" filter on click to enable
Talkback. We may need to uncheck it when user presses "Cancel" on
CustomContactListFilterActivity, to avoid 2 filters being checked at the
same time. This error doesn't occur on phones, and occurs only on tablets.
