ZEPPELIN-3345. Don't load interpreter setting when it exist interpreter.json 
but no interpreter-setting.json found

### What is this PR for?
It usually happens in dev enviroment. e.g. I have livy interpreter in 
interpreter.json due to history testing but no livy folder under 
`{ZEPPELIN_HOME}/interpreter` after I rebuilt the project without building livy 
module. This PR would just remove that invalid interpreter setting when loading 
from interpreter.json

### What type of PR is it?
[Bug Fix]

### Todos
* [ ] - Task

### What is the Jira issue?
* https://issues.apache.org/jira/browse/ZEPPELIN-3345

### How should this be tested?
* CI pass

### Screenshots (if appropriate)

### Questions:
* Does the licenses files need update? No
* Is there breaking changes for older versions? No
* Does this needs documentation? No
