Cleanup tests

When working on #11738 I noticed a few tests that needed to be cleaned up. It [was suggested](#11738 (comment)) to split the test changes into their own PR.

- `bad_config::bad1`
  - This was trying to match `config` which would get matched in the wrong place due to the test name having `config` in it
  - Fixed by making the match `/config`
- `build_script::panic_abort_with_build_scripts`
  - This test was failing as it was making sure `panic` was not in the output. After this change, it could match the test name and fail.
  - To fix this I updated it to look at `panic=abort` which appears to be what it was originally looking for (#5711). `@ehuss` please let me know if I misread what the test was testing.
- `cargo_command::cargo_subcommand_args`
  - This test had `#[test]` above `#[cargo_test]` which caused it to throw an error removing it fixed the issue

During this time I also ran into issues with `cargo_remove` tests being named `fn case()` which is different from how tests are normally named. I talked with `@epage` and it was decided that `fn case()` should probably be used for all `snapbox` tests since the unique test name is already the folder name. I went ahead and renamed all tests within `cargo_add/` and `init/` to match this style.

This PR should be reviewed commit by commit.
