* Support filtering annotations by display name

Allow `user:{term}` filters in the search bar to match display names as
well as usernames.

I have allowed for annotations having no `user_info` field as with other
code in the client that handles annotation objects. However "h" will always
populate that field currently.

Fixes https://github.com/hypothesis/product-backlog/issues/943

* Add tests to clarify how quotes are handled in filter query parsing

This came out of a Slack discussion [1] about how the client handles
quoted and unquoted terms in filter queries.

* Test that all matching annotations are returned for "user" queries

Respond to CR feedback to extend the current set of tests for "user"
queries.

Add tests for Authorization header on API requests

* Add profile.groups.read api endpoint

* Remove metadata from list groups api call

Rather than relying on the token of the logged in user being returned
as extra metadata from the list groups api call, simple use the profile
userid from the data store to determine whether a use is logged in or not.

* Add util/groups module with combineGroups helper

This will be used when the community-groups feature flag is set, to combine
groups from the groups list and profile groups endpoints.

* Add tests for util groups module

* Add tests for community-groups feature flag

Update Code Style docs to mention ESLint and Prettier

Only log names of source files that were changed as a result of
auto-formatting.

 - Advise developers to set up editor integrations for ESLint and Prettier
 - Remove the `eslint --fix` advice since most auto-fixable suggestions
   from ESLint are stylistic changes that are already handled by
   Prettier

`// eslint-disable-line` magic comments got moved down a line so they no
longer referred to the intended code. Switch to using
`// eslint-disable-next-line` instead.

Code formatting is now handled by Prettier.

Prettier is pinned to an exact version in package.json as per the advice
in Prettier's docs (see https://prettier.io/docs/en/install.html).
