refactor: Streamline location handling in AutocompleteAddressActivity (#998)

Removes the unnecessary nullable member variable `deviceLocation` and replaces it with a local, non-nullable variable within the `getAndCompareLocations` method.

This change improves null safety and adheres to more idiomatic Kotlin scoping practices, making the code cleaner and more robust without altering functionality.
