Faster diff rendering

1. Dont render link in separate template but use helper instead
2. Don't build new object but just reuse variables

New note for diff is rendered per each diff line. Such simple improvements gives us 20..100% better performance depends on diff size

Improve projects collecting

Refactor code that cause unexpected AR behaviour.

For example this works fine:

    @projects = Project.personal(@user).accessible_to(current_user)
    @groups = @user.groups.accessible_to(current_user) # OK

But

    @projects = Project.all
    @groups = @user.groups.accessible_to(current_user) # PG:Error

This reverts commit 23144389.
