This looks a test bug.
The test assumes destIFrame won't be refreshed, but it should refresh according to the specification. If destIframe is refreshed before sourceIFrame refresh, the test fails.

[html] Fix flakiness of moving-documents.html.

The test expected destIFrame wasn't refreshed. According to the standard and
dynamic-append.html in the same directory, destIFrame should be refreshed, and
the test failed if destIFrame was refreshed before sourceIFrame.

This CL updates moving-documents.html:
 - It doesn't move a meta, but just remove it.
  This test doesn't need to test 'remove and add' because dynamic-append.html
  covers 'add' part.
 - Rename it to remove-from-document.html.
