The tooling is offering to use runtime, that has been deleted

[zcervink]

• The tooling is offering to use runtime, that used to be part of a project (project and runtime has been deleted and the IDE has been restarted before this issue appears)
• The offered runtime is underlined with red line in the wizard (img no. 1 - on left half of the image)
• After I have opened the Edit Library window (using the Configure... button), I have deleted the invalid path using the minus button in the left bottom corner of the Edit Library window -> the library is still there, now it is no longer underlined (img no. 2)
• restart of the IDE or reinstalling the plugin does not help to solve this issue, the non-existing runtime is still present as it is captured on the img no. 2 (and the Edit Library window accessible using the Configure... button is empty)
• when I create new project using the non-existing library, new Quarkus project is created without any issue (except the fact that the runtime is not present in the newly created project)

Steps to reproduce:

1. Create new Quarkus project using New Project -> Java -> Quarkus -> Download library ......
2. Delete all the files including the runtime JAR file in the project using the IDE
3. Restart the IDE, invoke the New Project wizard and you should see what is captured on the img no. 1
