Regression: @{releaseLabel} variable is not resolved in the commit message of the branch goal

We get the following commit message since the upgrade to the release plugin 3.0.1 (from 2.5.3): "[maven-release-plugin] prepare branch @

" (see https://github.com/xwiki/xwiki-commons/commit/4e7eba27102a6c3c4954cf8dd7925232b8858157 for an example).

We used the following command line in this case:

    mvn release:branch -DbranchName=stable-16.0.x -DautoVersionSubmodules -DdevelopmentVersion=16.1.0-SNAPSHOT -DpushChanges=false -Pci,integration-tests,office-tests,legacy,standalone,flavor-integration-tests,distribution,docker

Before the upgrade, we used to get messages like "[maven-release-plugin] prepare branch stable-14.6.x" with the same command line (except for the versions related parameters values, of course).

The release prepare goal message which contains the same variable according to the documentation does not seem to have the same problem as we get "[maven-release-plugin] prepare release xwiki-commons-16.0.0-rc-1" (see https://github.com/xwiki/xwiki-commons/commit/716ed16279968ea1a251cfbcb200893f9f43735c for example) with command line

  mvn --batch-mode release:prepare -DpushChanges=false -DlocalCheckout=true -DreleaseVersion=16.0.0-rc-1 -DdevelopmentVersion=16.0.0-SNAPSHOT -Dtag=xwiki-commons-16.0.0-rc-1 -DautoVersionSubmodules=true -Plegacy,integration-tests,office-tests,standalone,flavor-integration-tests,distribution,docker
