neuronal restore: should not switch to image when in darkroom

[TurboGit]

I started a "neuronal restore" job on the lighttable. While computing was running I went to darkroom to edit some pictures.

But when the job ended, the image was loaded in the current filmroll, that's ok but also was made the edited picture on darkroom. This last behavior is unwanted.

@andriiryzhkov : One for you :)

Indeed unwanted behavior. Did not see this use case before. Thank you.
Fixed.
