fix broken docker-compose set up (re. FINERACT-773)

This fixed bugs introduced in edc9e03
(in apache#648) which for FINERACT-773
actually broke things more instead of adding the intended feature, cauz:

1. FINERACT_DEFAULT_TENANTDB_HOSTNAME and FINERACT_DEFAULT_TENANTDB_PORT
   were meant to be OS Environment Variables, not Java System properties
   and so need to be read via System.getenv() not System.getProperty(),
   duh!

2. The Travis CI test which was meant to ensure non-regression for this
   broke in that same change, because the "|| docker logs" introduced at
   the same time would always pass (EITHER because "http" passed OR
   if not then "docker logs" would return 0), duh again!

Both were dumb, not sure what I was thinking when I had hacked this.. ;)
