Breaks when doing composer update due to Silex 2.3

[nullbtb]

Hello,

I did a composer update recently which caused the version of Silex to update to 2.3. This resulted in my tests failing due to always returning 404 even though they always returned the correct body and X-Status-Code: 200.

Some debugging output from strace for a found match:

sendto(4, "HTTP/1.1 404 Not Found\r\nHost: localhost:8181\r\nDate: Wed, 02 May 2018 23:33:55 +0000\r\nConnection: close\r\nX-Powered-By: PHP/7.2.4\r\nSet-Cookie: XDEBUG_SESSION=10818; expires=Thu, 03-May-2018 00:33:55 GMT; Max-Age=3600; path=/\r\nCache-Control: no-cache, private\r\nDate: Wed, 02 May 2018 23:28:09 GMT\r\nX-Status-Code: 200\r\nContent-Type: text/html; charset=UTF-8\r\n\r\n", 357, 0, NULL, 0) = 357

My temporary fix was to lock silex in composer to 2.2.2: "silex/silex": "2.2.2",

Realized its the same as #46
