We were getting a few errors when trying out Zeitwerk:
```
expected file lib/sms_api.rb to define constant SmsApi
expected file app/components/layout/common_html_attributes_component.rb
to define constant Layout::CommonHtmlAttributesComponent
```
In these cases, we aren't using an inflection because we also define the
`Verification::SmsController` and a few migrations containing `Html` in
their class name, and none of them would work if we defined the
inflection.
We were also getting an error regarding classes containing WYSIWYG in
its name:
```
NameError: uninitialized constant WYSIWYGSanitizer
Did you mean? WysiwygSanitizer
```
In this case, adding the acronym is easier, since we never use "Wysiwyg"
in the code but we use "WYSIWYG" in many places.
We forgot to do so in commit d827768c0. In order to avoid the same
mistake in the future, we're extracting a method to get these
attributes. We're also adding tests, since we didn't have any tests to
check that the `dir` attribute was properly set.
We were very inconsistent regarding these rules.
Personally I prefer no empty lines around blocks, clases, etc... as
recommended by the Ruby style guide [1], and they're the default values
in rubocop, so those are the settings I'm applying.
The exception is the `private` access modifier, since we were leaving
empty lines around it most of the time. That's the default rubocop rule
as well. Personally I don't have a strong preference about this one.
