Creating group with problematic group name via graph api gives 500 error

[ScharfViktor]

ocis version 1.20 local

Steps:

• user tries to create group with name "?\?@#%@,;"

Expected: group was created

Actual: 500 with message: "message": "LDAP Result Code 2 \"Protocol Error\": failed to decode escaped character: encoding/hex: invalid byte: U+003F '?'"

Even if not really a duplicate. The route cause of this is basically the same as for: #4078

This particular test case seems to have been fixed by #4132 and was removed from expected-failures by oCIS PR #4198 and web PR owncloud/web#7275

@ScharfViktor please close if you agree that this is fixed.
