CSV export fails when (sub-)project name contains whitespaces

[catabu1]

Only confirmed for subprojects. There is a problem when the timesheet should be exported to csv and the time_entries are sorted by project.

The following is a related entry from the production log:

Completed 500 Internal Server Error in 227ms (ActiveRecord: 47.0ms)

NoMethodError (undefined method `name' for "Project / Subproject with Whitespaces":String):

I changed the line that's sorting the entries in the method to_csv to the following, which fixed my issues:

diff --git a/app/models/timesheet.rb b/app/models/timesheet.rb
index 84196d9..0e7b43e 100644

           end
         end
       when :issue
-        time_entries.sort.each do |project, entries|
+        time_entries.sort {|a,b| a[0].to_s <=> b[0].to_s}.each do |project, entries|
           entries[:issues].sort {|a,b| a[0].id <=> b[0].id}.each do |issue, time_entries|
             time_entries.each do |e|
               csv << time_entry_to_csv(e)

I'm no expert on ruby and I don't know if that's the cleanest solution possible (hence no pull request), but that's what fixed it for me for now.

Well, you are passing the options to string and , since we are putting them in .csv, its ok.
Ill test this , cause im making a modification of this plugin to filter the columns for both , the form and the .csv, and showing the custom fields.
