Since the test is both failing and crashing, I skipped it on mac-wk2 with <http://trac.webkit.org/projects/webkit/changeset/197152>

<rdar://problem/24874444>

[Brady Eidson]

This is the "DatabaseProcess uses too many file descriptors, therefore the SQLiteDB cannot be opened" bug that is being fixed in https://bugs.webkit.org/show_bug.cgi?id=154922

[Brady Eidson]

That was fixed in <http://trac.webkit.org/changeset/197474>

Unskipping this.
