POSTing to pluginManager/installNecessaryPlugins to install an older version of a plugin than the latest version will unexpectedly install the latest version.

For example, the latest version of the tfs plugin is 4.0, but I can't install an older version (ex. 3.2):

curl -X POST -d "<jenkins><install plugin=\"tfs@3.2.0\" /></jenkins>" --header "Content-Type: text/xml" http://localhost:8080/pluginManager/installNecessaryPlugins

The tfs plugin 4.0 is installed anyway.

I don't think any workarounds exist.
