[Location tracker] - Fix some location tracking issues

[mnaturel]

Your use case

What would you like to do?

Issues to fix :

• At start, use the latest known location of all available providers to avoid inconsistencies
• Prioritize locations received from the providers in the following order: “Fused”, “GPS”, other providers
• Debounce the location updates to avoid sending too many events
• Avoid calling callback for provider not available when only one of them is disabled (should be called only when all providers are disabled)

Why would you like to do it?

Using the last known location from all providers leads to notification of multiple locations with different accuracy and uncorrect location tracking.

How would you like to achieve it?

Select the best last known location to notify callbacks.
