checkAndUpdateSnapshotClass must always return a snapshot, even though it fails somewhere in ctrl.SetDefaultSnapshotClass. Add unit tests for that.

There was a problem hiding this comment.
Can you change to the following?
On error, it must return the original snapshot, not nil, because the caller syncContentByKey needs to check snapshot's timestamp.

checkAndUpdateSnapshotClassmust always return a snapshot, even though it fails somewhere inctrl.SetDefaultSnapshotClass-syncSnapshotByKeypanics with nil return. I tried to fixsyncSnapshotByKeyto allow nil return, but the resulting code was just ugly.While the real fix is one-liner in snapshot_controller_base.go, the PR is bigger due to test refactoring -
testCallmust have an opportunity to return a "fatal" error, even though a "normal" error is expected./kind bug
