No text input field displayed for direct-message type rooms to myselfe

### Steps to reproduce

1. Create a new room (without additional participants)
2. On Element Desktop enter the /converttodm command into this room

### Outcome

On Element Android the text input field for this room vanishes.

I expect that the text input field is displayed on Element Android as it is with Element Desktop.

(I am rather sure that this is a regression since some releases ago.)
