Description
There are problems with merging metro configs (some properties are overwritten).
For example:
as a result, the merged config contains only the custom sourceExts array, losing all rnv extensions (although initially, the logic implied unifying some of the properties).
This PR fixes such errors and improves the config merge flow.
