server Task Leaves Behind Old Plugins

[sghill]

In order to remove plugins effectively
As a plugin developer
I want the gradle-jpi-plugin to remove plugins from the work directory when they are removed from dependencies

Given I have a build.gradle like this:

plugins {
  id 'org.jenkins-ci.jpi' version '0.39.0'
}

jenkinsPlugin {
  coreVersion = '2.222.3'
}

dependencies {
  implementation 'org.jenkins-ci.plugins:git:4.0.1'
}

When I run ./gradlew server the git plugin
Then its dependencies are installed to work/plugins
When I remove the plugin and add another
Then the old plugin still remains in work/plugins
And is loaded by Jenkins

Fixed in the referenced commit by turning the copy plugins method into its own Sync task.
