When using the share/send to feature to Element, the app is started multiple times

### Steps to reproduce

1. Where are you starting? What can you see?

I have the element app running and go to another app, e.g. the photos app. I select an image and select share and choose a recipient channel on Matrix.

2. What do you click?

Then i post the image in the channel.

When I now look into the process list in the android view, the element app runs twice and it is started each time I use share again.

3. More steps…

### Outcome

#### What did you expect?

I expect the app to be used with the current instance and to post the image in the channel

#### What happened instead?

The image was posted in a new instance of the app and it then runs twice
