Title:
  Deadlock issues when 20-30 users copying collections & pages at the
  same time

Bug description:
  Multiple users on the forum have reported deadlock issues when there
  are many users (20-30) copying pages & collections at the same time.
  See
  https://mahara.org/interaction/forum/topic.php?id=7309&offset=0&limit=10

  Note that 20 to 30 users is around the number you'd hit if you're
  running a whole class of users through a training session at the same
  time.

  The three reported cases of this are all in 15.04, so it may be a
  problem introduced in that version.

  The problem has been reported in both Postgres & MySQL.
