Create empty state component
and use empty text for the table.

- Use let_it_be over let for performance
- Remove repeated, unnecessary code

- Remove the stub for `graphql_board_lists` from sidebar_spec.rb (EE).

This adds spec coverage for project issue boards when it is using
graphql-based boards code. A few selectors are added for testing
in sidebar components.

- Create a temporary spec for the classic boards

We will simply clone `sidebar_spec.rb` as `sidebar_deprecated_spec.rb`
and continue to provide the spec coverage for project issue boards (EE)
when it is using the classic boards code.

This commit introduces a caching on the Release LIST v4 API
in order to avoid repeated computation on the payload rendering.
