Use View Holder pattern in AccountsAdapter.getView().

Use View Holder pattern in AccountsAdapter.getView().

Currently, the lint warns at:
AccountsAdapter.java:29 Unconditional layout inflation from view adapter:
    Should use View Holder pattern (use recycled view passed into this method
    as the second parameter) for smoother scrolling: ViewHolder [warning]

This CL fixes the above lint error.
