Fix tests for 7.x-3.x

There were two instances of short-syntax arrays.

Yeah, that's annoying.

exception: [Warning] Line 228 of sites/all/modules/views/tests/views_cache.test:
simplexml_load_string(): Entity: line 2: parser error : XML declaration allowed only at the start of the document

That points to this line:

    $xml = simplexml_load_string($first_content);

.. and the variable comes from:

    $this->drupalGet('test_feed_http_headers_caching');
    $first_content = $this->drupalGetContent();

.. and test_feed_http_headers_caching is a view that comes from the views_test module. So this should work. I guess I need to run the tests locally to work out what's going on.

FYI I get the same error locally too.

I went back to 7.x-3.16 and ViewsCacheTest works ok there. Looking at the difference in the output, though, I wonder if the problem is simply a matter of unwanted whitespace? I added print_r($first_content) and there are more blank lines between the intro and the intro xml tag in the 7.x-3.x codebase than there are on 7.x-3.16.

Thanks for finding that, Stevel!
