Fix Widget configuration on new View (#2175)

When creating a new View, you can add Widgets to the areas, but you
cannot configure them. This is because Ajax request requires at least a
template-id, which is not provided; as the value is empty.

This PR addresses this, and updates the `templateid` and `formid` for
all the widget buttons. This provided the required context for being
able to configure the widgets.
