The @WithPlugins annotation is behaving inconsistently depending on the property uploadPlugins being set or not.

When a test requires a plugin version, if uploadPlugins=false, the test will install whatever version is available, even if it's older than the required one, and then the test will most probably fail because some functionality is missing.

We need to make it work the same way it does when uploadPlugins=true : it checks the available version is >= the required one, or skip the test if it is not.
