orgunit name untitled is preferred than dc.title

[floriangantner]

Describe the bug
OrgUnits with some dc.title are displayed as untitled (or it's corresponding translation)

To Reproduce
See

dspace-angular/src/app/core/breadcrumbs/dso-name.service.ts

Line 53 in 327a5bd

return dso.firstMetadataValue('organization.legalName') || this.translateService.instant('dso.name.untitled') || dso.firstMetadataValue('dc.title');

Expected behavior
We would expect the order
return dso.firstMetadataValue('organization.legalName') || dso.firstMetadataValue('dc.title') || this.translateService.instant('dso.name.untitled');
