Trying to use the repl features before newly started nodes have
riak_repl completely initialized leads to all sorts of nasty crashes and
noise. Frequently it makes fullsync stuck forever, which makes a lot of
the tests fail.
This also tweaks the AAE fullsync tests to remove assumptions about
failure stats when AAE transient errors occur. The behavior in the
handling of those errors has changed recently with the introduction of
soft exits.
As of commit 3044839456 tests that
return something other than the prescribed success atom 'pass' to
indicate success result in test failure. Change tests that return the
atom 'ok' or some other value to instead return 'pass' to indicate
success.
