MDL-33681 course: cannot have a section called '0'.

No reason to prevent this. It is just a matter of doing a proper test,
rather than the sloppy PHP !empty().
MDL-33682 backup: cope with sections called '0'

It was not previously possible to have a section called 0 because of
bugs in the standard course formats, but we hit this with the OU course
format. You got an exception because backup settings tested to see if
their lable was empty, which means a section name of '0' was fatal.
Should work now.
