…LIMIT during insertion (fix issue #52)

During insertion a check was done on dist_from_ideal_bucket to be sure
it doesn't becomes bigger than DIST_FROM_IDEAL_BUCKET_LIMIT but this was
only done during the robin swap. A check should also be done beforehand
if we find an empty bucket otherwise the variable could overflow and
lead to bugs. This commit adds this check.
