fix: remove duplicate conflicts test referencing uncreated file

The 'format shows conflicts' test in the Package DSL section ran
before /tmp/test_conflict.kap was created (it's created later in the
Conflicts section). Removed the premature copy — the Conflicts
section already has this test after file creation.
