Fix dynamic scene resources not being entity mapped (#18395)

Browse Source 
# Objective

The resources were converted via `clone_reflect_value` and the cloned
value was mapped. But the value that is inserted is the source of the
clone, which was not mapped.

I ran into this issue while working on #18380. Having non consecutive
entity allocations has caught a lot of bugs.

## Solution

Use the cloned value for insertion if it exists.
