Refactor and Correct Python-Sage-IMAP Tests

[sepehr-akbarzadeh]

The current tests for the python-sage-imap module have become outdated and are no longer effective following recent refactors. As a result, they are not providing any value and need to be completely corrected to ensure proper functionality and coverage.

2. Design New Tests:

   • Collaborate with the development team to understand the new and existing functionalities of the python-sage-imap module.
   • Design comprehensive test cases that cover all functionalities, including edge cases and error handling.

3. Implement New Tests:

   • Write new tests for the python-sage-imap module based on the designed test cases.
   • Ensure tests are written following best practices and are easily maintainable.

Expected Outcome:

• The python-sage-imap module should have a robust set of tests that accurately reflect its current functionality.
• All tests should pass successfully, ensuring the module's reliability and stability.
