Silence compiler gossip after nim upgrade cont1 (#1455)

* Silence some compiler gossip -- part 5, common

details:
  Mostly removing redundant imports and `Defect` tracer after switch
  to nim 1.6

* Silence some compiler gossip -- part 6, db, rpc, utils

details:
  Mostly removing redundant imports and `Defect` tracer after switch
  to nim 1.6

* Silence some compiler gossip -- part 7, randomly collected source files

details:
  Mostly removing redundant imports and `Defect` tracer after switch
  to nim 1.6

* Silence some compiler gossip -- part 8, assorted tests

details:
  Mostly removing redundant imports and `Defect` tracer after switch
  to nim 1.6

* Clique update

why:
  More impossible exceptions (undoes temporary fix from previous PR)
