Custom tmp dir is not respected

[esler]

Hello,
I need to create all tmp files into "non-standard" tmp folder, but options given to constructor are created to standard tmp dir.

Following test will not pass

<?php
    public function testThatTmpDirIsSetupBeforeCreatingTmpFile()
    {
        mkdir($tmpDir = realpath(sys_get_temp_dir()) . DIRECTORY_SEPARATOR . uniqid());

        $pdf = new Pdf(array(
            'tmpDir' => $tmpDir,
            'header-html' => "<p>I'm a content</p>",
        ));

        $this->assertInstanceOf('mikehaertl\tmp\File', $pdf->getOptions()['header-html']);
        $this->assertEquals($tmpDir, dirname($pdf->getOptions()['header-html']));
    }

@esler I've modified your fix and the tests a little. Can you check if this also works for you?

Fixed in 2.3.1. Thanks for you help.
