I've got an issue when using CopyArtifact plugin and Promoted builds plugin together.

I've configured a job with a promoted build parameter,
and added a step 'copy artifact from another project' to use build version specified by Permalink, and chose Permalink to be a promoted_build_name , not 'lastSuccessfulBuild'.
(that new dropdown list option has been added by Promoted build plugin).

When I start this job, I expect my job to copy artifacts from the specific promoted build version.
Instead, job always copies artifacts from the last successful promoted build.

Example:
I started a job and selected promoted build #19 as parameter.
In the console output I see that latest promoted build #21 artifacts have been copied.

I see BO_BUILD env variables pointing to correct #19 version,
and I see COPYARTIFACT_BUILD_NUMBER_ env variable pointing to wrong 21

I'm tagging both plugins since i'm not sure which one causes this problem.
