Name of cdk 3 adapter is different depending on using detection or adding manually

This is a followup of JBIDE-24447.

When cdk 3 is auto detected (typically when you start devstudio and ~/.minishift exists), the adapter will be created automatically with the name "Container Development Environment 3". On the other hand, if you choose to create the cdk 3 server adapter manually, the default name is "Container Development Environment". These should be consistent.
