Patch so default assignee can be a group

[VictorT83]

Redmine allows for groups to be set as the assignee for tasks, this plugin partially allows for the default assignee to be set as a group. The issue was that once selected It does not display the proper value.

I was able to select a group to be the default assignee for a project. However the default assignee selectbox would display blank. New tasks would be assigned to the group. So everything worked but displaying the group name. Here is a patch for this issue
