fix: Duplicate groups makes contact crash

[lforg37]

When some contacts have duplicated groups for the same items, the rendering crashes.

Context, one of my contact has the following (anonymized) VCARD (exported from proton web ui):

BEGIN:VCARD
VERSION:4.0
FN;PREF=1:John Doe
FN;PREF=2:John Doe
TEL;PREF=1:+33666666666
TEL;PREF=2:+33999999999
TEL;PREF=3:+33 1 23 45 67 89
N:;;;;
UID:proton-android-3794338e-4fc7-426f-a6c1-8eabaa54e63f
ITEM1.EMAIL;TYPE=home;PREF=1:abcde@gmail.com
ITEM2.EMAIL;PREF=2:abcde@gmail.com
PRODID;VALUE=TEXT:-//ProtonMail//ProtonMail vCard 1.0.0//EN
ITEM1.CATEGORIES:Family
ITEM2.CATEGORIES:Family
ITEM1.CATEGORIES:Family
ITEM2.CATEGORIES:Family
END:VCARD

Trying to open the detail view for this contact makes the application crash with the following trace:

java.lang.IllegalArgumentException: Key "Family" was already used. If you are using LazyColumn/Row please make sure you provide a unique key for each item.
