refactor: update exportRESTCollections method signature

- Drop the `collections` parameter since the it is already available in the `PersonalWorkspaceProviderService` context.
- Make the above method return a left error of `NO_COLLECTIONS_TO_EXPORT` when the collections list is empty.
- Error handling updates.
