By using a tree with multiple identical files and allowing copy detection to
choose any one of them, the check in the test is unnecessarily complex. We can
simplify by:
* Modify source file (file2) before copying the file.
* Check that only file2 is the source in the output of "p4 filelog".
* Remove all "case" statements and replace them with simple tests to check
that source is "file2".
