I agree. Maybe the best solution would be to allow setting a default activity per project?

Here's a simple patch which removes blank field if only one activity is present:

diff --git a/app/helpers/timelog_helper.rb b/app/helpers/timelog_helper.rb

     end
     activities.each { |a| collection << [a.name, a.id] }
     collection
