Fix GoogleLocationEngine intermittent delayed updates

[andrlee]

Reset default displacement value to 0 due to potential delay with first location update on Pie that takes 30 seconds - 1 min. We've not seen this behavior on pre-Pie api versions, so the assumption is that changes in framework were made that no longer work well with default displacement value we had tested with previously.

Thanks for the quick 👀 here @andrlee

In order to confirm that this was the issue causing the lag, would it make sense trying to reproduce #348 setting the displacement to 3.0f in the snippet that seems fixing it (FusedLocationEngine mapbox/mapbox-navigation-android#1764 (comment))?

In any case, this looks good to me 👍

@Guardiola31337 i was not able to repro this on emulator running Pie and i don't have hardware with Pie installed at hand. I asked @electrostat to help with testing though. May i suggest something? Can you ask your customers who have reported this to explicitly setDisplacement to 0 in their LocationEngineRequest object and retest?
