- Earlier, shipping calculator was getting displayed based on the isAddressComplete value.
- For the scenarios where address was incomplete but formatted address was present shipping calculator was not getting displayed.
- This made shipping calculator not getting displayed for guest shoppers.
- With this, conditions are changed from isAddressComplete to formatShippingAddress to display shipping calculator if formatted address is present.
- Add unit test case for the condition for formatted address.

- Update the comments to add the reason to hide shipping calculator.
- When there is no default customer location in the store and the customer has not entered their address, but there is a default shipping method available for all locations, then we will hide the shipping calculator.
