This is an attempt to solve the test failures on Launchpad's CI.
I'm assuming when we do a redirection like
foo > file
and then try to execute `file` immediately afterwards, we either
haven't written it soon enough or closed the file, so we get a "text
file busy" error.
So, when we do that in a new fish the file should be closed once it
quits.
See #8021.
