An agent's activity history lies about total number of builds

Steps to reproduce

1. View the activity history/recent builds page of an online agent that has run more than 25 builds.
2. Ensure the page is set to "Showing Last 25 builds" (which is the default).

Actual results

Note that at the bottom of the page the pagination section:

• it reports "Showing 1-25 of 25", and
• the "next" and "last" arrow links do not link to anything.

Changing the results list to show "All builds" will show the actual number of builds (i.e. the true number, which is higher than 25) and the "next" and "last" arrows will work.

This is deceptive and confusing because the user thinks that the 25th build at the bottom of the list is the first build the agent ran, even though this is not the case. This makes debugging agent problems very frustrating.

Expected results

The pagination section should report the correct total number of builds (e.g. "Showing 1-25 of 452" and the "next" and "last" icons should link to the respective pages.

Note that other view options ("Showing X days", or "All builds") do not have any problem.
