Youtube iframe without data-param-* causes warning

[naeh]

Hello,

when trying de convert html containing youtube iframe without any data-param-* it causes warning, here is an example of youtube tag :
<iframe src="http://www.youtube.com/embed/zA_19bHxEYg" width="425" height="350"></iframe>

here is the warning :
Warning: Invalid argument supplied for foreach() in lullabot\amp\src\Pass\IframeYouTubeTagTransformPass.php on line 161

the problem is that BasePass::getQueryArray returns bool or array but this is not controlled when used in IframeYouTubeTagTransformPass

i think that BasePass::getQueryArray must always return an array (even empty)
