Fix `Input` to allow scalar shape.
The primary use-case is for models that include their pre-processing, and expect a batch of strings as input (like most of the tensorflow_hub text modules).
In python the empty tuple (a scalar-shape) is Falsey.
This change avoids the "ValueError please provide a `tensor` or `shape`" error when the user provides an empty shape.
