feat: Add occ user:user:sync-account-data for updating oc_accounts in…

…formation from user backends

This can be useful in cases where the state between user backend and
oc_accounts has become inconsistent.

Usually the account data is updated once the change on the user backend
is detected. Potential leftovers from older bugs
(nextcloud/user_saml#582) might though never get
updated. This could lead to the contacts menu never showing the correct
display name. The contacts menu is read from the system address book,
which is only updated from oc_accounts.
