Branch/Tag/Commit selector: Show more summary is not displayed

Created by: umpox

Steps to reproduce:

1. Open the Branch/Tag/Commit selector on the 'Commit' view where there are multiple pages of commits

Expected behavior:

• 'Show more' button is displayed
• Summary text is displayed: e.g. X commits total (showing first 50)

Actual behavior:

• 'Show more' button is displayed
• Summary text is not displayed

Notes:

• When debugging this, it seems that the summary text is created, but only when 'Show more' is clicked. It should display at all times, unless we are loading more results
