Handle whitespaces somehow

` @my @your` instead of `@my @your` now. It could be fixes as well checking parent node but for directives parent is always not null - it is `Directives` container, so actually grand parent is needed. Moreover, even after such check some tests failed (see `Printer_Should_Print_Pretty_If_Directives_Skipped`). The core problem is that some arbitrary nodes **can be** skipped so it's not obvious how to handle whitespaces at all. General approach may be to require each node to print their leading whitespace if it should do that. Downside - it will complicate all printing code. I do not want to do that just to handle very rare cases.
