Is "contact phethelp@colorado.edu" a real license?

Promoting TODO to an issue:

(also see https://github.com/phetsims/sherpa/issues/64#issuecomment-583150392)

While looking into un-issued TODOs in chipper, I found a todo added from this issue to reportThirdParty.js:

    // TODO: is this a real license?  Why is there logic here but nowhere else?  Perhaps files annotated with
    // TODO: contact phethelp@colorado.edu are leaking into the HTML files unnecessarily, see https://github.com/phetsims/sherpa/issues/64
    if ( license !== 'contact phethelp@colorado.edu' ) {
      mediaOutput.push( mediaEntryLines.join( '<br>' ) );

      if ( mediaLicensesUsed.indexOf( license ) < 0 ) {
        mediaLicensesUsed.push( license );
      }
    }
  }

This todo and if statement were added by @samreid, so assigning there.

I checked a built file and it did not include leak those files licensing information into the HTML file unnecessarily (other than the asset). It's unclear where we would want to factor out usage of that license text for usage elsewhere, but we can always factor it out if we find a site later. I'll remove the TODOs for now.

Removed the TODO, closing.
