Hi,

with the current release of 8.7.17 the newly introduced ".form.yaml"-extension and the FilePersistenceSlot disallows removing a form-configuration if there is a recycler bin in your folder structure.

This use-case leads to:

#1530281202: Persisting form definition "1:/user_upload/_recycler_/testform.form.yaml" is denied

Current workflow in ext:form on FormManagerController::deleteAction is calling ResourceStorage::deleteFile through FormPersistenceManager::delete.
If there is a "nearestRecyclerFolder" deleteFile will delegate to moveFile but in filePersistenceSLot::onPreMoveFile -> assertFile there is no invocation allowed for this combination (none defined and also none allowed).

A quick (and really dirty) workaround is calling defineInvocation inside of FilePersistenceSlot::onPreFileMove - but this allows moving ".form.yaml" always and should not be used on production environment.

Possibly also a bug in 9.x - not yet tested
