Roborock Integration: AttributeError due to incorrect handling of cached data

[cloudbr34k84]

The problem

I encountered multiple errors related to the Roborock integration in Home Assistant. The first issue is an InvalidStateError, which seems to occur when handling RoborockFuture callbacks. The second issue is an AttributeError when processing scheduling times from the cache. These errors appear in the logs without any specific user action triggering them.

Steps to reproduce:

1. Configure the Roborock integration.
2. Let the integration run.
3. Observe the log for errors, particularly those related to cached data and time values.

Expected result: The integration should correctly handle the cached data and manage the scheduling time without errors.

Actual result: The integration throws multiple exceptions, including an InvalidStateError when resolving future callbacks and an AttributeError when retrieving start_hour and start_minute from cached data.

The invalid state error is tracked in #119733 and humbertogontijo/python-roborock#222 -- we can keep this about the attribute error.
