Make the following changes to deal with new behavior in Rails 4.1.2:

* Use nested resources to avoid slashes in arguments to path helpers.

signe-in -> signed-in
go_to_gihub_for_permissions -> go_to_github_for_permissions
descendand -> descendant
behavour -> behaviour
recepient_email -> recipient_email
generate_fingerpint -> generate_fingerprint
dependes -> depends
Cant't -> Can't
wisit -> visit
notifcation -> notification
sufficent_scope -> sufficient_scope?
levet -> level

This was default before but now it fixed with providing assignee_id
parameter making url shareble and dont reset when other filters users.

Also this commit removes old methods that are not used any more.
