fix #4858
add specs for escaping auto_completion
no need for params[:format] = :json in the autocomplete view spec
also use pry-byebug for mri_21
Added default sorted scope to Status, so whenever statuses are
retrieved without any ordering parameter, they should be sorted
automatically
Removed now-redundant specification of Status sort order
