4784: Change management of test cfg to better support json projects r=Nashenas88 a=Nashenas88
This helps support json projects where they can decide whether to add the `test` cfg or not. One alternative is to add support for marking json project crates as a sysroot crate, and adding logic to remove the `test` cfg in those cases. In my opinion, that option gives less flexibility to json projects and leads to more functionality that needs to be maintained.
Fixes#4508

4740: Remove unneeded "./" prefix affecting error messages r=kjeremy a=dtolnay
I noticed this in the error in the commit message of https://github.com/rust-analyzer/rust-analyzer/pull/4739.
Before:
```console
error[E0599]: no method named `initialize_finish` found for struct `lsp_server::Connection` in the current scope
--> crates/rust-analyzer/./src/bin/main.rs:99:16
|
99 | connection.initialize_finish(initialize_id, initialize_result)?;
| ^^^^^^^^^^^^^^^^^ method not found in `lsp_server::Connection`
```
After:
```console
error[E0599]: no method named `initialize_finish` found for struct `lsp_server::Connection` in the current scope
--> crates/rust-analyzer/src/bin/main.rs:99:16
|
99 | connection.initialize_finish(initialize_id, initialize_result)?;

My codebase already depended on lsp-server and introducing a dependency
on rust-analyzer failed at first because it assumes some functions that
were first present in lsp-server 0.3.2.
Without this change:
error[E0599]: no method named `initialize_start` found for struct `lsp_server::Connection` in the current scope
--> crates/rust-analyzer/./src/bin/main.rs:83:57

83 | let (initialize_id, initialize_params) = connection.initialize_start()?;

Eventually, we should support "just open random rust file" use case,
we don't really do this now, so let's avoid spending time on it until
we fix it properly.
