Migrated SubscriptionItem from FS to erp5_open_trade: this is the contract as
in https://www.erp5.com/erp5-TechnicalNote.Open.Order#contract and make
erp5_payroll depends on erp5_open_trade as Employment Contract is a
SubscriptionItem and, per design, Payroll is kind of an Open Order.

ERP5TypeInformation are used for Portal Types of Portal Types and needed to generate at
least Workflow Methods early at Zope startup (initializePortalTypeDynamicWorkflowMethods()
and portal_type_group_filter in the problem reported on MR 1032) for very basic Portal
Type classes (such as Category Tool). So, Leave these on the filesystem for now, we can
eventually deal with them later if necessary.

There is no need to crash the renderjs interface for an error not related to the interface itself.

contentValues() nowadays return also non ERP5-ish objects such as python
scripts , OFS.File etc. Because of that, if an ERP5 Folder contained a
non ERP5 object, which does not have fixConsistency or checkConsistency
methods, Folder.checkConsistency was causing an infinite loop because it
was acquiring checkConsistency method from self.

so that it is more user friendly for user following the convention.

Again for user friendliness, we sort the lists alphabetically also

Sometimes these API fail, but that's not so important, what matters is marking commits as success or failure at the end of test.

erp5_accounting is installed before auto-configurtion and is unreliable thus use erp5_trade which certainly is installed by configurator.
