New tests for copy recursive with absolute paths

Absolute path trailing slash handling in absolute directories

find_needle() isn't passing a trailing slash through verbatim.  Since
copy uses that to determine if it should copy a directory or just the
files inside of it, we have to detect that and restore it after calling
find_needle()

Fixes #27439
