Error 500 while importing csv with empty fields

[ralgozino]

If you tru to import csv with empty cells, the plugin fials with error 500, and you can see the following message in the log:

ActionView::Template::Error (undefined method `force_encoding' for nil:NilClass):
    26:         <% @csv_rows[0].each_with_index do |value, index| %>
    27:           <tr class="<%= cycle('odd', 'even') %> issue child parent">
    28:                     <td> <%= value.force_encoding("utf-8") %> </td>
    29:                     <td> <%= @csv_rows[1][index].force_encoding("utf-8") %> </td>
    30:                     <% @options = params[:options][index] if params[:import] %>
    31:                     <td>
    32:                       <%= select_tag :options, options_for_select(@query, :selected => @options), {:name => "options[]", :prompt => "No Match (Skip)"} 

It would be better to check if the cell is empty before trying to (de|en)code de text.
