Use custom filter when filter isn't saved

- includes misc UI fix on tablet. width isn't set
  correctly.

TESTED (needs the change above):
- keep contacts visibility after GB to ICS migration
- keep filter option between People and Phone UI
- keep filter option after People/Phone reboot (killing the process)

REMAINING ISSUES:
- Custom filter affects "All contacts" filter.
  For example, if the user choose "All contacts" after showing
  "Other contacts" using custom filter (in Google directory),
  "Other contacts" will be shown (while it sholdn't).
  "All contacts" should show contacts inside default_directory,
  or at least it shouldn't be affected by previous custom filter
  choice.
- Phone filter still shows "Other contacts" (with phones)
  unxpectedly, which should be fixed.
