Remove ContactDetailLayoutController's social code

Prior to this change, the ContactDetailLayoutController
used ViewPagers and Carousels to display nothing but the
ContactDetailFragment. Originally these ViewPagers and carousels
were used to display social code.

I have removed the now useless ViewPagers, carousels and adapters.

Now that ContactDetailLayoutController's layout only contains
the ContactDetailFragment, there is no need for multiple different
ContactDetailLayoutController layouts.
