> MappingServiceImpl#nodesSetRef might contain an empty set when mapping if the logical topology event hasn't occurred yet. This results in colocation targets having {{nodes}} equal to 0, so no targets are colocated, even if they are supposed to be. This results in 'ColocationMappingException: Targets are not colocated' (thrown in AbstractTarget:123, as of commit b9bd1c4db01a5377190b363c208375d845890265).
> This is easily reproducible locally with ItDataSchemaSyncTest#checkSchemasCorrectlyRestore()
