Show actual commit count on project dashboard

## What does this MR do?
Instead of displaying the rounded commit count this shows the actual commit count on the project dashboard.

## Why was this MR needed?
The rounded commit count is great for a quick display of the commits, such as for the public project list. However, for the dashboard it is overly simplified. When a project has between 1,000 and 5,000 commits you just see '1000+ commits'. There is no reason we shouldn't show the complete commit count here.
