Locate me icon: Use coarse location if available

[pataquets]

Description:
When clicking location icon with disabled GPS, an "activate GPS" request message pops. This happens even if coarse, noon GPS location is already enabled.
If the user doesn't want to activate and wait for GPS fix, coarse location could be used instead. In populated areas, coarse location from nearby WiFi and cell radios can provide good enough precision and users can save battery.

Steps to reproduce:

1. Make sure location is enabled, but no GPS accuracy level is on.
2. Click location icon.
3. Enable GPS dialog pops up.
4. Dismiss by clicking Cancel

Expected behavior:
Use available coarse location info to proceed, do nothing if location is turned off.

Actual behavior:
No location info is used, even if coarse location available, so nothing happens.

Environment:
Moto G5
Android 7

Version:
3.0.19 from Play store

Looks like it's fixed in e95faaa , but I can't see the new version in Google Play to test it.
