🐛 CDP Browsable API doesn't return valid DAD-IS link with spaces in breed_name

[bunop]

An entry with spaces in URLField (such the dadis_url attribute at https://api.image2020genebank.eu/backend/dadis_link/1/) doesn't render correctly URLs with encoded spaces in templates. This beaviour seems depends by the urlize template tags, which is called in rest_framework/templates/rest_framework/base.html to render a string formatted like this (not a JSON but a <pre> formatted text):

{
    "url": "http://localhost:26081/backend/dadis_link/1/",
    "species": {
        "scientific_name": "Ovis aries",
        "common_name": "Sheep"
    },
    "supplied_breed": "Schoonebeek heath",
    "country": "Netherlands",
    "most_common_name": "Schoonebeeker Heideschaap",
    "transboundary_name": "Schoonebeek heath sheep",
    "other_name": [],
    "dadis_url": "https://fao-dadis-breed-detail.firebaseapp.com/?country=Netherlands&specie=Sheep&breed=Schoonebeeker%20Heideschaap",           
    "is_custom": true
}

more precisely, urlize cant represent the encoded space %20 in the href link:

from django.utils.html import urlize
urlize("https://fao-dadis-breed-detail.firebaseapp.com/?country=Netherlands&specie=Sheep&breed=Schoonebeeker%20Heideschaap")
# '<a href="https://fao-dadis-breed-detail.firebaseapp.com/?country=Netherlands&amp;specie=Sheep&amp;breed=Schoonebeeker+Heideschaap">https://fao-dadis-breed-detail.firebaseapp.com/?country=Netherlands&specie=Sheep&breed=Schoonebeeker%20Heideschaap</a>'

The returned link (in which %20 is changed in +) is not a valid dad-is permalink
