fix for Container dev_solr invalid start port '8983:8983': invalid syntax

This PR had a defect in it:

- #928

Now commands like this should work fine, which was the original intent:

curl http://localhost:8983/solr/collection1/schema/fields

See doc/sphinx-guides/source/container/running/demo.rst under
"Additional Metadata Blocks" for related commands.
