Handle Units when returning fullStreetAddress

[hwong103]

When searching for addresses with unit numbers the autocomplete finds the correct address, however the component doesn't appear to retain the Unit when outputting the full street address.

Having looked into the Places API it does seem to be returned by the API under the subpremise address_component however it's not referenced by the component to combine into the full street address. It'd be great if this could be included when returning the selected address
