Bug#367098: PTS: bug summary should not count merged bugs twice

[Thijs Kinkhorst <kink@squirrelmail.org>]

Package: qa.debian.org
Severity: minor

Hello all,

The PTS shows a summary of the bug numbers for a package, however if a
package has two bugs which are merged, it displays 2. I'd expect 1 to be
a better summary of the state of affairs.

regards,
Thijs
