Fix collection access issues for owner/admin users

The implementation of the `Manager` user type (#1242) introduced a regression
whereby owner/admin users are incorrectly denied access to certain collection
APIs if their access control for collections isn't set to "access all".

Owner/admin users should always have full access to collection APIs, per
https://bitwarden.com/help/article/user-types-access-control/#access-control:

> Assigning Admins and Owners to Collections via Access Control will only
> impact which Collections appear readily in the Filters section of their
> Vault. Admins and Owners will always be able to access "un-assigned"
> Collections via the Organization view.
