GitLab

When detecting if the school will be refuted or not it's necessary
to check the /etc/prd_version file. If the version is the 1.1 or some
2.0rc, the school must be refuted.

The problem happens when the school should not be refuted, but the
return statement wasn't work like expected, and the script keep
runnning, bloking the school.

Removing the return command and adding a block based "if" command
has solved this issue.
