Fixes output message when successfully added a new metadatum
When adding a new metadatum to an existing record via kadi-apy, the output message was "Metadata were not changed" although the new metadatum was added.
> kadi-apy records add-metadatum -h "https://kadi4mat.iam-cms.kit.edu" -k $my_token -r 334 -t "integer" -m "another_key" -v "123" -u "beans"
Metadata were not changed.
