New DMs not always marked as such

#### Describe the bug
Sometimes when creating a DM via Element Android, it is not actually marked as a DM, which means it sticks around in the rooms part of the app. I have noticed it this time when pressing the "Direct message" button in a user's room profile.

#### To Reproduce
Steps to reproduce the behavior:
1. Go to a user's profile in a room
2. Click on "Direct message"
3. Wait for the DM to be created (actually, some feedback here would be nice)
4. See that what was created is in fact a normal room not a DM

#### Expected behavior
The room should be marked as a DM in all cases

#### Smartphone (please complete the following information):
- OS: Android 10

#### Additional context
- App version and store: 1.1.7 PlayStore Beta
- Homeserver: an-atom-in.space

Not sure if reproducible 100% of the time but happened to me around 2 times now total (bearing in mind that I don't open a lot of DMs).

Also, if anyone can tell me how to convert said room to a DM, that would be appreciated :D
