Interface crashes if authors of attachments were given ORCIDs about metadatamanagement

[moellerth]

Documentation of the problem:
When adding an attachment, a dialog opens. By selecting the attachment type "Method report" author metadata including the search for ORCIDs can be added. This search is implemented as another dialog. Displaying multiple dialogs at the same time is not a standard behavior, so the attachment dialog is automatically closed as soon as the ORCID dialog opens. It will not reopen once an ORCID has been selected.

Solution:
Displaying multiple dialogs is allowed manually for ORCID search, which will keep the attachment dialog open during the search process.

ORCID mapping works well, but cannot fully be tested because the release fails in the test system #3217
