Improve initial setup to trigger more bugs

[juliusknorr]

As @nickvergessen mentioned there could be a couple of things to configure to trigger bugs

• Set a displayname on the users, maybe displaynames with some xss teststrings

• File skeleton with special characters

• TODO: Collect more

• randomize darkmode setting on user creation
• upload image avatars (still no OCC/OCS endpoint, Talk ships its own)
• I personally use random for user id and login via configured email address
  • uuids (helps with visuals)
  • add spaces (problem in URLs, needs to be encoded)
  • numeric only (problem in arrays as keys in PHP https://3v4l.org/8dTd1 )
  • double @ user ids, e.g. break@ing@every@thing (problem with federation splitting user + domain from cloud ids)

USERID=$(uuidgen)
TEST5=$USERID
sudo -u www-data OC_PASS="123456" ./occ -vvv user:add --password-from-env --display-name "Emily Evans" -g $GROUPID1 -g $GROUPID2 $USERID
sudo -u www-data ./occ -vvv user:setting $USERID settings email test5@example.tld
