Find x?.something.orEmpty() patterns

Recipe IDorg.openrewrite.kotlin.idiom.FindOrEmptyAfterSafeCall$KtRecipe
Artifactio.moderne.recipe:recipes-kotlin

x?.something.orEmpty() mixes safe-call and a null-coalescing extension. Either drop the ?. (if x is non-null) or chain through ?: emptyList() — the mix obscures which call is providing the fallback.
