chore(release): 7.0.3 (#2915)

* Deploy server default is `bundleDependencies: true`, correct this when generating the functions package.json
* `onMessage` callback should fire in the ng zone
* Auth was wrapping exports it wasn't suppose to
* Don't fail the deploy if there isn't an `index.html` file
* Lazifying the sample
* Cleaning up user-agent reporting
* Marking the samples as autogenerated, to reduce noise
* Committing the firebase/rxfire/base.ts files for easier readability
* Version and changelog entry
* Test cleanup and get storage emulator working
