Code review comment for lp:~bac/launchpad/bug-639703-pg-bugs

Thanks Brad and Henning. This is a very nice fix and I am very pleased we fixed some 3.0-ism too. As Henning pointed, we want a consistent experience:

The page should show the owner the same help link as is shown on projects:
    (i) Getting started with bug tracking in Launchpad.
    <https://help.launchpad.net/Bugs>

There is a secondary issue that help does not explain exactly what bug tracking features project groups provide. Actually, Lp has a poor understanding of what PGs provide. I think PG documentation is a secondary issue. We will discuss PGs over the next few months and decide their fate.
