Generating samples main crashes if GAN didn't have electrode label

[chadcwilliams]

Joshua noticed a bug where if you don't give an electrode label to the GAN, the generate_samples script still expects one.

Below you will see on line 256 it includes kw_channel in the created list but this is empty so the length is smaller than the data (or maybe it's the other way around).

Solved. The problem was not that it expected an electrode but that the conditions-field has changed in the case for no conditions from being an empty list conditions = [] to conditions = ['']. Therefore, it added the condition '' and had one field too much.
