Ignores the file shared from OsmAnd (points of interest list)

[OsmAnd](https://github.com/osmandapp/OsmAnd) is a map navigation app based on OpenStreetMap. Sharing the list of Points of Interest ([how-to](https://docs.osmand.net/en/main@latest/osmand/personal/favorites#export--import)) sends an intent (code is [here](https://github.com/osmandapp/OsmAnd/blob/f29edbcbc56d54af71636fe812fdaa1e9b9dc73a/OsmAnd/src/net/osmand/plus/activities/FavoritesTreeFragment.java#L718)) made of

1. the subject `Favorites shared via OsmAnd`
2. the list as free-form plain text:
```
Point of interest 1 - geo:-71.1949,61.817707
...
```
3. the same list as a GPX file

Messaging apps handle it like so:
- Telegram sends the plain text and the file (2 and 3)
- WhatsApp sends the file, not the plain text (3, not 2)
- Element sends the plain text, not the file (2, not 3)

This is a problem for the receiving user, because the list cannot be imported into any application (OsmAnd or other app) as it's a free-form textual description.
