currently, the code checks if there are three empty strings - 'side', 'layer' and 'boardLocation' - in the first entry of the 'replacedWires' or 'badSolderJoints' field
if so, the entire field is replaced by an empty list, since the empty strings would indicate that no wires or solders have actually been entered
HOWEVER, because the 'layer' sub-field has a default value in the type forms, this will never be an empty string ... and so there will always be an entry in the list, even if no wires or solders have indeed been entered
the check on the 'layer' string has now been removed ... the 'side' and 'boardLocation' string checks remain, since they can be empty (and will be, if no wires or solders have been entered)
