Bug 1486839 [wpt PR 12724] - HTML: document.open() and history entry …

…creation, a=testonly

Automatic update from web-platform-testsHTML: document.open() and history entry creation (#12724)

The 010.html test has been removed for a multitude of reasons:

- It does not seem to work as intended in any browser. (I.e., no browser
  passes the test.)
- The concept it allegedly tests (salvageability) is no longer in the
  specification for document.open().

For whatwg/html#3946.
