General issue report

Hi team,
when provisioner reset ble mesh node then not all data from persistent store are deleted. At least those data are kept:

• bound App key for all models
• publication address for all models

I (1668) BLE_MESH: Friend not supported
I (1732) BLE_MESH: Restored mesh device role: Node
I (1735) BLE_MESH: Restored Model Bound AppKey, index 0000
W (1736) BLE_MESH(lib): Managed flooding policy
I (1737) BLE_MESH: Restored Model Publication, address 0xc000, app_idx 0x000
I (1744) BLE_MESH: Restored Model Bound AppKey, index 0000
I (1749) BLE_MESH: Restored Model Bound AppKey, index 0000

W (1760) BLE_MESH(lib): Managed flooding policy
I (1764) BLE_MESH: Restored Model Publication, address 0xffff, app_idx 0x000

After re-provisioning those data are restored in new mesh network, but this is most likely undesirable.

Thanks
