REGRESSION(r67176): editing/selection/doubleclick-inline-first-last-contenteditable.html crashes
https://bugs.webkit.org/show_bug.cgi?id=45525
The crash was caused by ancestorToRetainStructureAndAppearance not taking into consideration
the case where there is no common block ancestor. Fixed this by adding a null check.
Test: editing/pasteboard/copy-without-common-block-crash.html
* editing/markup.cpp:
(WebCore::ancestorToRetainStructureAndAppearance): Added a null check.

REGRESSION(r67176): editing/selection/doubleclick-inline-first-last-contenteditable.html crashes
https://bugs.webkit.org/show_bug.cgi?id=45525
Added a test to ensure WebKit does not crash when copying a region that doesn't have any common block ancestor.
Also removed doubleclick-inline-first-last-contenteditable.html from the qt's skipped list since
this test should not crash anymore.
* editing/pasteboard/copy-without-common-block-crash-expected.txt: Added.
* editing/pasteboard/copy-without-common-block-crash.html: Added.
* platform/qt/Skipped: Removed doubleclick-inline-first-last-contenteditable.html from the list.
