[LayoutNG] Fix ComputedStyle::ShouldUseTextIndent()

This patch fixes a typo that calls the default constructor instead of
the getter when the logic was copied from BreakingContextInlineHeaders.

This code path is used only in LayoutNG. Tests in fast/css3-text/css3-
text-indent/ still fail for other reasons when LayoutNG is enabled.
