Fix sandboxing of redirection tests (#11407)

Browse Source 
When running `cargo test --workspace` a file `crates/nu-command/a.txt`
remained which we also saw as an accidential additions in some commits.

Searching for `a.txt` narrowed it down that
`redirection_keep_exit_codes` was not sandboxed in a temporary directory
and created this file.

Went through redirection tests and placed them in a `Playground` to get
sandboxing `dirs` for `nu!(cwd:`.
For those tests where redirection fails and no file should be created
now I added a check that no file is created on accident.


- Sandbox `redirection_keep_exit_codes` test
- Sandbox `no_duplicate_redirection` test
- Check that no redirect file is created on error
- Sandbox `redirection_should_have_a_target` test
