Folders plugin blocks job creation

User is unable to create a simple job while using a docker image or the war file (and possibly also a standard installation, I did not check that)

This prevents following https://jenkins.io/doc/pipeline/tour/getting-started/ which makes it a higher priority bug since it prevents adoption of Jenkins by new users.

How to simulate:

1. execute java -jar jenkins.war --httpPort=8080
2. enter the temporary password on the Jenkins page
3. use 'Install suggested plugins' option during setup
4. setup new user
5. click on 'New item'
6. Enter name and choose for example 'Multibranch pipeline', click [OK]
7. The configuration page never loads completely, the 'LOADING' stays displayed

INFO: Failed to instantiate optional component com.cloudbees.hudson.plugins.folder.properties.FolderCredentialsProvider$FolderCredentialsProperty$DescriptorImpl; skipping

Request that fails with 500:

http://localhost:8080/job/job1/configure

Workaround:

Use the 'Select plugins to install' during the setup and uncheck Folders plugin.
