[16.0][MIG] account_statement_import_online_adyen
This PR includes some changes to other modules to prevent interference with the workings of this module.
Note that the migrated import of statements has been tested and has extensive user tests, but that the bare minimum has been done for the technical migration of the account_statement_clearing_account module, as I have no extensive knowledge of reconciliation in 16.0.
There hasn't been any activity on this pull request in the past 4 months, so it has been marked as stale and it will be closed automatically if no further activity occurs in the next 30 days. If you want this PR to never become stale, please ask a PSC member to apply the "no stale" label.
@StefanRijnhart Could you have a look at this one and reopen it? Maybe even review and merge it?
