### Steps to reproduce

1. Activate E2EE in android client / have it already activated and use it in android client to "cache/ save" the keys locally
2. Reset E2EE on the server (Settings -> Security -> End-to-end encryption)
3. Use the client E2EE encryption to encrypt for example a new folder

### Expected behaviour

After step 3 should generate new key pair and should generate a new passphrase because E2EE was reset and keys on server were deleted

### Actual behaviour

App uses local keys and not generates new ones as it should. The E2EE is on the server side not activated (eg. resetting is not possible anymore) but client behaves like it is activated.

Explanation of the video: After 15 sec I reset e2ee, folder is deleted as it should be but encryption a new folder works fine while server has no e2ee keys

### Additional information

I think e2ee implementation is missing a check before doing anything to see if server still has e2ee keys and if they are the same as the local ones.
