Silence compiler gossip after nim upgrade cont3 (#1466)
* Removed some Windows specific unit test annoyances

details:
+ Short put()/get() cycles on persistent database have a race condition
  with vendor rocksdb. On a specific (and slow) qemu/win7 a 50ms `sleep()`
  in between will mostly do the job (i.e. unless heavy CPU load.) This
  issue was not observed on github/ci.
+ Removed annoyances when qemu/Win7 keeps the rocksdb database files
  locked even after closing the db. The problem is solved by strictly
  using fresh names for each test. No assumption made to be able to
  properly clean up. This issue was not observed on github/ci.

* Silence some compiler gossip -- part 7, misc/non(sync or graphql)

details:
  Adding some missing exception annotation
