LPS-45425 Delete log because it is providing user wrong information because the thumbnail could had been found with other parameters.

Hey @danielkocsis , 

can you check this pull? 

I'm deleting this log because the method exportThumbnail(...) it been called 3 times with different parameters and we found that in some cases it is founding a thumbnail in one of the cases but not for the others. 

I've agreed with @sergiogonzalez that this could be redundant or ever worse, confusing for the user, because it seems that no thumbnail has been found and this is wrong.

Do you think that it could hava side effects, or even better, could we reformat the code to avoid call this logic 3 times (to improve performance)?

Thanks!!!!!
