Min value not reset to source when recreating device

[Heizelmann]

When recreating a device from device edit dialog the min value is set always to zero although a source value not 0 exists. Mean and max value are reset correctly.

When a device is recreated all stats are reset to 0 by design. I'll have a look into this later to understand why it does not seem to work in your case.

But that is not OK in my opinion. Min, max and mean should be set to source. For mean and max this is already done, For min not.
