`mvnd help:evaluate` regression

`mvnd help:evaluate` doesn't print anything anymore since `1.0-m7-m39`

To reproduce, setup a basic project:
```shell
mvn archetype:generate -DgroupId=com.mycompany.app -DartifactId=my-app -DarchetypeArtifactId=maven-archetype-quickstart -DarchetypeVersion=1.4 -DinteractiveMode=false
cd my-app
mkdir .mvn
```

then run `mvnd help:evaluate -Dexpression=project.version -q -DforceStdout`

using SDKMAN, it looks like it was broken in `1.0-m7-m39`:

```shell
~ sdk use mvnd 1.0-m6-m40

Using mvnd version 1.0-m6-m40 in this shell.
~ mvnd help:evaluate -Dexpression=project.version -q -DforceStdout
[INFO] [stdout] 1.0-SNAPSHOT
~ sdk use mvnd 1.0-m7-m39

Using mvnd version 1.0-m7-m39 in this shell.
~ mvnd help:evaluate -Dexpression=project.version -q -DforceStdout
```

Reproduce the regression in a generated Maven project with `mvnd help:evaluate -Dexpression=project.version -q -DforceStdout`, then compare the output between versions `1.0-m6-m40` and `1.0-m7-m39`. Trace the mvnd changes between those versions that affect this command's stdout handling; done means the command prints `1.0-SNAPSHOT` again.
