False warning: unnecessary use of `cloned`

Summary

warning: failed to automatically apply fixes suggested by rustc to crate `dispenser`

after fixes were automatically applied the compiler reported errors within these files:

  * src/main.rs

This likely indicates a bug in either rustc or cargo itself,
and we would appreciate a bug report! You're likely to see
a number of compiler warnings after this message which cargo
attempted to fix but failed. If you could open an issue at
https://github.com/rust-lang/rust-clippy/issues
quoting the full output of this command we'd be very appreciative!
Note that you may be able to make some more progress in the near-term
fixing code with the `--broken-code` flag

The following errors were reported:
error[E0597]: `instances.inner` does not live long enough
  --> src/main.rs:53:25

   | |______________- argument requires that `instances.inner` is borrowed for `'static`
57 |           }
58 |       }
   |       - `instances.inner` dropped here while still borrowed

Start by reconstructing the reported src/main.rs case and running cargo clippy --fix --bin "dispenser" to confirm the unnecessary_to_owned suggestion and resulting E0597 error. Trace the lint's handling of .iter().cloned() in the Clippy source and add a regression test showing that the suggestion must not produce code that fails to compile.
