When a ClearCase project is ClearQuest enabled, the contributing activities for
Integration Activities (deliver, rebase) are not reported.

In UcmActivity, the isIntegrationActivity is based on whether or not the "name"
property of an activity starts with "deliver." or "rebase.". This assumption is not
correct when the project is ClearQuest enabled because ClearQuest will insert the
ClearQuest ID into the "name" field.

One solution is to check the "headline", however there is the possibility that a user
will start the name of his activity with "deliver" and that may fail. Also looking up
the headline will require one extra lsactivity call (afaik).

Another solution is to check if it is an UCMUtilityActivity, but I dont know how to
get that information. (May also only apply to ClearQuest activities...)
