"expected" DCO denis checks for does not match what is actually generated by the config from the container

[charliemirabile]

the containerfile pulls the students full name from the orbit db to initialize the user.name field for the git config so the SOB for e.g. john_smith would be Signed-off-by: John Smith <john_smith@course.domain> and not Signed-off-by: john_smith <john_smith@course.domain>

We could fix this by just not using the real name field in the containerfile, or we could change the denis code to lookup the correct value.

Well at this point it's too late to change orbit's continerfile, so we'll have change denis.
