Fixing array reference bug in recommendations.pm

Attached patch fixes a small reference bug in Recommendations.pm (included in
the previous patch) that only occurs when we have more recommendations than the
limit (default value of 100)

$res = \@{ @{$res}[0..$limit] } if (@$res > $limit);

will cause an error as it tries to interpret the items within $res as arrayrefs
when they are hashrefs. What we really want to do is shorten our results down
to never be longer than limit:

$res = [ @{$res}[0..$limit] ] if (@$res > $limit);
