Fix soroban-test integration tests to make sure the full suite is being run in CI/CD

I noticed that when running cargo test --package soroban-test --test it locally, or in a GH Action, not all of the tests seem to run. The output looks like this:

running 50 tests
test arg_parsing::parse_bool ... ok
test arg_parsing::parse_i32 ... ok
...
test arg_parsing::parse_u32 ... ok
test arg_parsing::parse_u64 ... ok
test config::generate_key_on_testnet ... ok
test arg_parsing::parse_enum_const ... ok
test arg_parsing::parse_enum ... ok
test arg_parsing::parse_i256 ... ok
test arg_parsing::parse_obj ... ok
test config::seed_phrase ... ok
test config::read_key ... ok
Example contract method which takes a struct
Usage Notes:
Each arg has a corresponding --<arg_name>-file-path which is a path to a file containing the corresponding JSON argument.
Note: The only types which aren't JSON are Bytes and BytesN, which are raw bytes

Usage: strukt_hel [OPTIONS]

Options:
      --strukt <{ a: u32, b: bool, c: Symbol }>
          This is from the rust doc above the struct Test
          Example:
            --strukt '{ "a": 1, "b": true, "c": "hello" }'

  -h, --help
          Print help (see a summary with '-h')

The output doesn't include the final test result including the number of failed and passed tests (i.e. test result: FAILED, 31 passed; 10 failed;...), nor does it include the status of all of the config tests, or any of the build, init, plugin, or version tests.

After digging a little bit, it seems like something in the help.rs file is causing this, though I'm not 100% sure what is going on. It looks like help.rs is potentially capturing the stdout (and maybe stderr too), so that the rest of the test output doesn't make it to the command line.

I discovered this because there are a couple of tests that should be failing now, but they aren't.

Repo steps

To see this, comment out the tests in help.rs and you'll see that there are some failing tests. I'm not sure if all of them are valid failures, but the error inversion.rs looks legit.
