Session start error after deleting an application

Steps to reproduce:

1. Log in using this method:
2. Use this method from GitHub matrix-its-sdk repo to start session
3. Delete application without logout.
4. Install app again and log in using method in point 1.
5. Stop the app and run it again.

Error log:
🚨 [MXCryptoV2] start(_:failure:): Failed starting crypto module Error Domain=org.matrix.sdk Code=6 "One time key signed_curve25519:AAAAAAAAACE already exists.

Sometimes SDK even crashes

Start with the listed reinstall and session-start reproduction, then trace the MXCryptoV2 start failure and the one-time-key upload request shown in the error log. Done means the app can be stopped, relaunched, and start a session after deleting and reinstalling an application without the duplicate-key error or crash.
