Fix issues with GitHub actions tests

Trying to fix three issues here with the GitHub actions test run:
1. 'DJANGO_SETTINGS_MODULE' variable not set. I've corrected this in
   the `build_ci_settings.sh` file.
2. The 'manage-test' docker-compose service appeared to get built in the
   middle of the init-dockerdata process, when it should have been fully
   built as part of the previous step. I changed the order of services
   in that previous build step to put 'manage-test' first. I'm not sure
   if this will have any effect.
3. Had one failing test, in exporter task integration tests -- the
   number of expected chunks that tasks got broken into didn't match
   reality. In my own testing environment I have a couple of extra
   settings that set the max batch size, which would probably have a
   direct effect on how many chunks get produced. I copied this setting
   into the `build_ci_settings.sh` file.
