Prior to this fix if a map-based class or style binding wrote
its values onto an elemenent, the internal styling context would
not register the binding if the initial value as a `NO_CHANGE`
value. This situation occurs if a directive takes control of the
`class` or `style` input values and then returns a `NO_CHANGE` value
if the initial value is empty.
This patch ensures that all bindings are always registered with the
`TStylingContext` data-structure even if their initial value is
an instance of `NO_CHANGE`.
