Yuri Astrakhan eb3970285b fallout: fix tests to allow uninlined_format_args
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
