Fix DeleteCollaboration transaction behaviour (#28886) (#28889)

Backport #28886 by @KN4CK3R The method can't be called with an outer transaction because if the user is not a collaborator the outer transaction will be rolled back even if the inner transaction uses the no-error path. `has == 0` leads to `return nil` which cancels the transaction. A standalone call of this method does nothing but if used with an outer transaction, that will be canceled. Co-authored-by: KN4CK3R <[email protected]>
