Choose Profile Back Arrow Not Working

[kayaelle]

Describe the bug
When claiming a credential, you are first asked to choose a profile. Clicking on the back arrow doesn't do anything. There's no way to exit.

To Reproduce
Steps to reproduce the behavior:

1. Use a deeplink to open the LCW -- like the link/QR code on a claim page
2. This should open the choose profile screen
3. Click on back arrow in top left corner.

Expected behavior
Not sure where the back arrow should lead to because this screen displays in response to an attempted claim of a credential. One recommendation is to remove the back arrow and instead display the navigation bar at the bottom of the screen like we do on other screens. But we should explore other ways the choose profile screen is triggered. For instance, it is likely triggered by the add credential screen and in that case, the back arrow makes sense.
