Added @ operator to silence notice from tempnam()

[AndrewCarterUK]

So I'm not sure about this one, but on my machine I was getting the following error running the test suite:

andrew@ANDREW-LAPTOP-DEBIAN:~/Development/PHPFastCGI/FastCGIDaemon$ vendor/bin/phpunit 
PHPUnit 7.2.7 by Sebastian Bergmann and contributors.

................................................E                 49 / 49 (100%)

Time: 7.17 seconds, Memory: 6.00MB

There was 1 error:

1) PHPFastCGI\Test\FastCGIDaemon\Http\RequestTest::testMultipartContentWithMultipleFiles
tempnam(): file created in the system's temporary directory

/home/andrew/Development/PHPFastCGI/FastCGIDaemon/src/Http/Request.php:167
/home/andrew/Development/PHPFastCGI/FastCGIDaemon/src/Http/Request.php:127
/home/andrew/Development/PHPFastCGI/FastCGIDaemon/test/Http/RequestTest.php:250

ERRORS!
Tests: 49, Assertions: 178, Errors: 1.

It looks like tempnam() is throwing out a notice to say it created the file - which is being converted to an error by the test suite.

I guess an alternative approach would be to change the PHPUnit configuration - but I'm wondering if any frameworks might also get pestered by this notice and it's best just suppressing it?

Thank you. It seams fair. We are checking he success of the upload anyways.
