Tests fail after a clean install

Hi, first time installing the repository.

Environment:
- Linux (centos 7)
- Installing in a custom Docker container
- Conda installed
- server runs and returns:
```
{"created": "TIME",
"lastModified": "TIME",
"root": "GUID",
"hrefs": [{"rel": "self", "href": "http://localhost:5000/"}, {"rel": "database", "href": "http://localhost:5000/datasets"},
{"rel": "groupbase", "href": "http://localhost:5000/groups"}, {"rel": "typebase", "href": "http://localhost:5000/datatypes"},
{"rel": "root", "href": "http://localhost:5000/groups/GUID"}]}
```

I added the git repo root to PYTHONPATH to try and run tests (needed to be added to import h5serv, please update docs)

When running tests I had the following failures:
- datasettest
- testGetBool
- testGetEnum
- attributetest
- Test 2,3,4,5,6,7,8,10,11,12,13,15,16,17,18,19,20,21,22,23,29,30,33 Fails
- Test 9 Errors
- acltest
- testAttributes

Again, this is in my own docker container, so not sure if there is a docker configuration (ie. a port other than 5000 that should be open) that could be causing these failures.

Thanks
