Fall back to default text when no command is available for the resolved lens (#57790)
Follow-up to https://github.com/zed-industries/zed/pull/54100

LSP [code
lens](https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#codeLens)
has the only textual data in
[`command`](https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#command),
which we use for rendering (`command.title`).

Certain language servers do not send the command by default until
resolved, and this is the only field worth resolving in the code lens
which we have to fetch asynchronously as the user types.

Not including such lens at all caused flickering and
https://github.com/zed-industries/zed/pull/55075 had dealt with this by
reserving the block for all code lens and swapping them with the
resolved data later.

Yet, certain language servers return empty commands even after
resolving, to indicate "nothing referencing this", as it is shown in
VSCode:

/>

Before, we have removed blocks for such lens with no command after the
resolve, but this caused flickering as reported in
https://github.com/zed-industries/zed/pull/55075#issuecomment-4549779927

Thus, this PR falls back to the placeholder for such lens, to avoid any
flickering and odd empty blocks.
Also, this PR reworks the tests to have the assertions more readable.

Licensing

License information for third party dependencies must be correctly provided for CI to pass.

We use cargo-about to automatically comply with open source licenses. If CI is failing, check the following:

  • Is it showing a no license specified error for a crate you've created? If so, add publish = false under [package] in your crate's Cargo.toml.
  • Is the error failed to satisfy license requirements for a dependency? If so, first determine what license the project has and whether this system is sufficient to comply with this license's requirements. If you're unsure, ask a lawyer. Once you've verified that this system is acceptable add the license's SPDX identifier to the accepted array in script/licenses/zed-licenses.toml.
  • Is cargo-about unable to find the license for a dependency? If so, add a clarification field at the end of script/licenses/zed-licenses.toml, as specified in the cargo-about book.

Sponsorship

Zed is developed by Zed Industries, Inc., a for-profit company.
