fix(upgrade): fix AngularJsUrlCodec to support Safari (#32959) 

Safari throws an error when the new URL() constructor is called with an
undefined base. This change checks whether the base is undefined and
then calls the corresponding version of the URL constructor.

fix(upgrade): simplify solution by replacing undefined with ''

Simplify solution by replacing undefined with ''

fix(upgrade): Avoid passing an empty string as the base as well.

Browsers other than Safari may have issues with the empty string.
