Fix DecoratedCustomViewStyle with 1-2 actions

When using 1-2 actions, createRemoteViews would
incorrectly use the MAX_ACTION_BUTTONS (3) for the
number of actions. To support 1-2 actions, use the
min() of the number of actions and MAX_ACTION_BUTTONS.

Test: Tested DecoratedCustomViewStyle with 1 action.
