Review comment:
ditto, it clearer to use if else here
```
case u @ UnresolvedFunction(nameParts, ...) =>
val CatalogAndIdentifier(catalog, v2Ident) = nameParts
def lookupPersistentFunction(): Expression = if
(CatalogV2Util.isSessionCatalog(catalog)) {
processFunctionExpr(v1SessionCatalog.lookupFunction ...

if (nameParts.length == 1) {
v1SessionCatalog.lookupBuiltinOrTempFunction....map(...).getOrElse(lookupPersistentFunction)
} else {
lookupPersistentFunction
}
