If the public view URL contains an incorrect viewcode, some pages produce an internal error.

Examples:

• https://bib.rero.ch/rbjn/ill_requests/new?record_pid=882620
• https://bib.rero.ch/rbjn/user/profile
• https://bib.rero.ch/rbjn/user/password
• https://bib.rero.ch/rbjn/documents/882620
• https://bib.rero.ch/rbjn/entities/remote/1317323
• https://bib.rero.ch/rbjn/documents/882620/export/json?prettyprint=True
• https://bib.rero.ch/rbjn/documents/882620/export/ris?prettyprint=True

Expected behavior:
