Bring backward compatibility for request profiles

It seems that we missed the backward compatibility support
for profiles in the existing folder.

This commit also fixes some specs to be idempotent
and work in a temporary directory which not always
seems to be the case.

This commit also brings the profile_spec.rb which seems
to be missing.
