Fixed disappearing drawer toggle

When the activity is recreated after it was stopped in background,
the BackStackEntryCount is the same for all fragments. The one that
should display the toggle therefore thinks it shouldn't. This change
saves the button state now. This is only needed for top-level fragments.
