Subject: Fix short-lived regression in xmlStaticCopyNode

Commit 7618a3b1 didn't account for coalesced text nodes.

I think it would be better if xmlStaticCopyNode didn't try to coalesce
text nodes at all. This code path can only be triggered if some other
code doesn't coalesce text nodes properly. In this case, OSS-Fuzz found
such behavior in xinclude.c.
