Subject: [PATCH] APIv4 - Flush navigation caches after writing or deleting
 navigation item

Historically the expectation was that this cache gets flushed manually.
I've kept that unchanged for legacy code (v3 create/delete and direct BAO::add)
but with APIv4 and onward the cache will get flushed automatically after a write operation.
