The application crashes when clicking the image being Encrypting

#### Expected behavior
Supposedly, when I click on the image being encrypted the application will not crash.

#### Actual behavior
Initially, when I send a picture via "Choose from Library" and still in Encrypting process, I click on the image to ensure it, the application suddenly crashes and exits by itself.

#### How to reproduce
1. Install apps and lists
2. Next go to the team menu, and do "Create team" or "Join the team".
3. Next go to the chat page
4. Next do image sending via "Choose from Library"
5. While the image is in the process of Encrypting, click on the image, then the application will crash.

Start with the chat image-send flow and reproduce the crash while the image is encrypting, using the supplied recording and Android Logcat trace. The React Native stack points to a raw-text child being added during layout; done means clicking the in-progress image no longer crashes the application.
