untranslated message when bulk validation completes

[archaeogeek]

Describe the bug
In Geonetwork 3.4.x, if you run the bulk validation from the contribute menu then when the process completes a green message flashes up saying [object object]. It disappears too quickly for me to investigate.

To Reproduce
Steps to reproduce the behavior:

1. Go to the contribute menu and select one or more records.
2. In the selected records menu select validate.
3. Click "yes" in the dialog that confirms whether you want to validate the records
4. See the message flash up as validation completes.

Expected behavior
A translated message, presumably saying something like "Validation has completed"

Screenshots
It disappears too quickly for me to get a screenshot

I think it's necessary to parse the object returned from the server to get the message to show, on this line:

core-geonetwork/web-ui/src/main/resources/catalog/components/metadataactions/MetadataActionService.js

Line 165 in 78ceda8

alertResult(data.data);

This error is still presenting in 3.6.0
