tests: Test AnsibleUnsafeText when copying files larger SMALL_FILE_LIMIT

The bug was fixed in a previous commit by Jonathan Rosser. This adds testing.
The bug is only triggered when the copy module is used inside a `with_items:`
loop and the destination filename has an extension. A `loop:` loop is not
sufficient.
