Dynamic Spatial Frequency not working with dependent actors

In UReplicationGraphNode_DynamicSpatialFrequency::CalcFrequencyForActor, the ActorChannelCloseFrameNum is updated for the actor but not its dependents when calculating FramesTillReplicate. As a result, dependent actor's channels will get closed before the next time ReplicateSingleActor is called.

Create a Dynamic Spatial Frequency node and add it to the RepGraph.
Add an actor to this node that has another actor as a dependent.

Expected: When the frequency drops, the actor and its dependents are replicated as normal at that frequency.
Actual: When the frequency drops, dependent actors are destroyed and then recreated.
