Search failed if address book's name contains a space

Describe the bug

I have 2 address books : one called "Contacts", the other one called "Contacts Communs" (its name contains a space)
Using unified search, I cannot display a contact if it belongs to the address book with a space in its name.

To Reproduce
Steps to reproduce the behavior:

1. Create an address book with a space in its name, like "Contacts Communs"
2. Create a contact inside that address book
3. Search this contact (with the unified search) and click on it in the search result

Expected behavior
The contact details should be displayed.

Actual behavior
An error message 'Contact not found' is showed.

Note that if the address book's name doesn't contain a space, everything works fine.

Server configuration

Operating system: Debian Buster (10)

Web server: Apache 2.4.38

Database: PostgreSQL 11

PHP version: 7.3.19

Nextcloud version: 20.0.4

Contacts version: 3.4.2

Updated from an older Nextcloud or fresh install: Updated

No errors have been found.

Start by reproducing the unified-search flow with an address book named "Contacts Communs", then trace how a search result opens contact details and how the address-book name is handled. Done means contacts from address books containing spaces open normally instead of showing "Contact not found".
