bug fix preserve fileObject CSV controls

When using AbstractCsv::createFromFileObject
the CSV object inherit the SplFileObject csv controls

A php bug was filled because SplFileObject::getCsvControl did not
return the escape caracter (see: https://bugs.php.net/bug.php?id=72646)

The bug is resolved so the patch can be completely applied and the testsuite
is updated accordingly
