Gem::Version raising ArgumentError for weirdly versioned Jenkins plugins...

Hi there,

we ran into the same issue with a dependency (jquery 1.7.2-1) upon installation of the build-pipeline-plugin. This fix addresses the issue around Gem::Version in both :install (covered in @autodesk-azepeda's PR) as well as install_plugin_from_update_center in the plugin library (which was not covered).

Do let me know if you have any further questions or remarks - thanks in advance for merging this in!

Kind regards,
David
