Virtual keyboard overlaps map view when choosing location to send

## Steps to reproduce
1. Open chat with someone
2. Open keyboard by tapping on text field
3. Choose attachments button
4. Choose location
5. Map opens partially covered by keyboard (most importantly, the buttons to choose the location to send are covered)

### Expected behaviour
The map should be visible.

### Actual behaviour
The map and the buttons are not visible because they are covered by the virtual keyboard and there is no method to dismiss it from the map view.

#### Notes:
- in the right screenshot I have **not** tapped on the search bar
- this bug seems to only affect the location attachment, I have tried with all the other types but they work fine even with an open keyboard in the chat view

| If I open the location screen without tapping on the text field beforehand (keyboard closed) | If I open the location screen having tapped on the text field beforehand (keyboard open) |
