Interpolator test same as default

[Jacopostortini]

When trying to add an interpolator to see the difference we are actually adding the default interpolator so there is no difference

1. Go to chapter "Tweak motion of front layer" MDC 104 - Add Motion
2. Try running the code without adding the interpolator and adding the interpolator
3. See no difference

I expected to see a difference, and I would have seen it if the tutorial had suggested a different interpolator like AccelerateInterpolator, DecelerateInterpolator or LinearInterpolator

• Level MDC-104
• Language Java -https://codelabs.developers.google.com/codelabs/mdc-104-java#4

Not really a bug, just a consideration to avoid confusion
