Modify LastUpdateTime when the Sealed Secrets is being updated (#1475)

**Description of the change**

This PR modify the way that we are setting up the LastUpdateTime. We are
going to modify the LastUpdateTime always that we are updating the
Sealed Secrets and the LastTransitionTime only when the status has
changed.

Integration tests included.

**Benefits**

LastUpdateTime is working properly
