environment-modules is less featureful than Lmod.

Select the default version in a different way since environment-modules
    didn't understand the symlink
  Ignore error messsages in the shell startup script as environment-modules
    prints an error message if a module has already been loaded.  The command
    is doing the right thing for this case except that it's also printing an
    error message.
