trydiff: check only if added file is a copy target, not source

When creating a diff with copy/rename enabled, we consider added files
and check if they are either copy sources or targets. However, an
added file should never be a copy source. The test suite seems to
agree with this: all tests pass if we raise an exception when an added
file is a copy source. So, let's simplify the code by dropping the
conditions that are never true.

For those interested in the historical reasons:

Before commit d1f209bb9564 (patch: separate reverse copy data
(issue1959), 2010-02-11), 'copy' seems to have been a bidirectional
map. Then that commit split it up into two unidirectional maps and
duplicated the logic to look in both maps. It was still needed at that
point to look in both maps, as the copy detection was poor and could
sometimes be reported in reverse.

A little later came 91eb4512edd0 (copies: rewrite copy detection for
non-merge users, 2012-01-04). That commit fixed the copy detection to
be backwards when it should, and made the hacks in trydiff
unnecessary.
