[bug] - apps contact - download a contact group's is impossible

[lsoulas]

Hi,

since to upgrade contacts app in 4.0.1 version,
it’s impossible to download a groupe.
I tested with Firefox and Chromium. Two browsers viewing next error:

TypeError: Cannot read property ‘xxxxxxx-xxxx-xxx-xxxx-xxxxxxxxxxx~contacts’ of undefined
at GroupNavigationItem.vue:92
at Array.forEach ()
at o.downloadGroup (GroupNavigationItem.vue:91)
at click (GroupNavigationItem.vue?vue&type=template&id=3bde8da3&:1)
at Vt (vue.runtime.esm.js:1863)
at o.n (vue.runtime.esm.js:2188)
at Vt (vue.runtime.esm.js:1863)
at o.t.$emit (vue.runtime.esm.js:3903)
at onClick (ActionButton.js:66)
at Vt (vue.runtime.esm.js:1863)

Thank you for your help.
