UAnimInstance::GetInstanceTransitionTimeElapsed returning 0 in non-editor builds

In non-editor builds UAnimInstance::GetInstanceTransitionTimeElapsed always returns 0.0f.

This is caused within FAnimNode_StateMachine::Update_AnyThread due to:

#if WITH_EDITORONLY_DATA
 NewTransition->SourceTransitionIndices = PotentialTransition.SourceTransitionIndices;
#endif

These wrappings around SourceTransitionIndices were removed in 4.13(CL 3082579) for [Link Removed], however this instance seems to have been missed.

Call UAnimInstance::GetInstanceTransitionTimeElapsed or UAnimInstance::GetInstanceTransitionTimeElapsedFraction in a non-editor build for a valid state machine and transition.

Result: Always returns 0.0f
