[TFGSUMIT]

Title: Fixed RedisException error with error handling

Description:
This pull request addresses the RedisException error in the nextcloud/notes-android repository by adding error handling in key locations. The changes involve adding try-catch blocks in the MainActivity, ItemAdapter, and ExceptionHandler classes to prevent note content from being replaced with error messages.

Changes:

• Added error handling logic in MainActivity, ItemAdapter, and ExceptionHandler classes
• Updated logging to display RedisException errors

Testing instructions:

1. Run the app with RedisException errors to verify that the error handling logic works correctly.
2. Verify that the app remains stable and user-friendly even in the presence of RedisException errors.
3. Test that the note content is not replaced with error messages when RedisException occurs.

Please review and test this pull request to ensure that the changes meet the requirements and do not introduce any new issues.
