When calling `Files\Node\Node::copy()`, `Files\View::copy()` gets called,
but `Files\View::fakeRoot` is empty so the hooks are not emitted if no
path is given to `Files\View::shouldEmitHooks()`.
This results in node-related events like `NodeCopiedEvent` not being
fired when copying files via `Files\Node\Node::copy()`.
`Files\View::shouldEmitHooks()` is given a path as parameter in almost
all places except when called from the `copy()` function. This commit
changes it and passes the copy target path.
