Level Instance Property Overrides failing in UWorldPartitionLevelStreamingDynamic::FinalizeRuntimeLevel

See addl info URL for a repro project & steps on how to use it.

Essentially, create a level with 2 level instances created from another level. That level should contain an actor with a level instance overridable property. When overriding one of the properties, the level in PIE will run as expected. When the project is re-started, a check is hit in UWorldPartitionLevelStreamingDynamic::FinalizeRuntimeLevel() during PIE.
