`viewTest.php` API request fails for long requests

[williamjallen]

Bug report

Expected Behavior

Accessing moderately-sized lists of tests on viewTest.php should not print an error in the browser console.

Actual Behavior

When visiting viewTest.php for builds with a large number of tests, the developer console currently displays an error due to a failed API call. The corresponding API call includes a large number of request parameters, and exceeds the maximum request size, resulting in a 414 (Request-URI Too Long) response. The page does not seem to be visibly broken when this error occurs.

I observed this behavior on the VTK dashboard on open.cdash.org.

Further investigation is necessary.
