NOMDL forum: fixed the string wording to match the current code condition
Previous string was used together with the legacy:guest capability.
However, the current code checks is_enrolled() instead. This led to a
weird situation when non-enrolled admin or manager could not subscribe
to a forum and the error message was completely confusing for them.
