Fix: Non-UTF8 ID breaking the WatermelonDB roles collection.

[OtavioStasiak]

Proposed changes

The solution to fix the WMDB issue involves encoding non-UTF8 IDs to ensure they are properly handled. Before sending them to the Redux dispatch, the non-UTF8 IDs are decoded. Additionally, if the roles collection is already corrupted, the code now resets the collection and refills it, ensuring smooth operation.

How to test or reproduce

• Run the code without my updates and edit the getRoles function at line 84 to force a role with a non-UTF8 ID. Update the code to include:

roles.push({
    _id: 'テストDb壊れた', // Non-UTF8 characters in ID
    description: 'Admin',
    mandatory2fa: false,
    protected: true,
    scope: 'Users',
    name: 'admin'
});

• Restart the app. You should see an error occur due to the non-UTF8 ID.
• Apply my updates, restart the app, and observe. If the error occurs once, the roles collection will reset, and getRoles will execute again without errors.
