I've just updated symfony/http-foundation dependency from 3.2.8 to 3.3.10, and tests at random place just broke, previously was working with expectation of 'http://localhost/test', now it became 'http://localhosttest'. I'm using getUri method.

I made some research, so I updated to 3.2.13 (seems working version). then I updated to 3.3.0 version (broke), and tried to find in history who deleted '/', but nothing interested found, just addition, but not removal, at commit symfony/http-foundation@9077baf#diff-7edb274bc39ed8c493badba7dd278826

+        if ($requestUri !== '' && $requestUri[0] !== '/') {
+            $requestUri = '/'.$requestUri;
+        }

I'm using getUri method, which uses that discussed preparePathInfo method. More over I found another missing slashes commits:
symfony/http-foundation@9077baf#diff-7edb274bc39ed8c493badba7dd278826
symfony/http-foundation@4665cb9#diff-7edb274bc39ed8c493badba7dd278826
symfony/http-foundation@742db41#diff-7edb274bc39ed8c493badba7dd278826L1849

Please clearify is it missing or deleted for real but no reference to it?
