Two small patches for the News section of the website

Hello,

the attached patches propose the following changes:

account_views.patch:

This modifies the https://www.postgresql.org/account/ website, and shows
"Items not submitted yet" and "Items waiting for moderator approval"
only when there is actual content. Empty boxes are not shown.

objectlist.patch:

This updates https://www.postgresql.org/account/edit/news/ , fixes a
missing </p>, and separates the "Submit for moderation" link from the
item link to make it clear that these are two different things.
It also updates the description above the items, and adds a note that
items must be submitted, if there are items.

Both patches are untested, as I couldn't get the pgweb working locally.

Regards,
