Removing the `.as_ref()` or `.as_mut()` as the top-level expression in a
closure may change the type of the result. In this case, it may be
better not to lint rather than proposing a fix that would not work.
In order to switch `clippy::uninlined_format_args` from pedantic to
style, all existing tests must not raise a warning. I did not want to
change the actual tests, so this is a relatively minor change that:
* add `#![allow(clippy::uninlined_format_args)]` where needed
* normalizes all allow/deny/warn attributes
* all allow attributes are grouped together
* sorted alphabetically
* the `clippy::*` attributes are listed separate from the other ones.
* deny and warn attributes are listed before the allowed ones
changelog: none
