Renaming file causes FileNotFoundException on java language server start

##[provide a description of the issue]

Environment

• Operating System: 10.12.2
• JDK version: jdk1.8.0_121
• Visual Studio Code version: 1.9.1
• Java extension version: 0.0.10

Steps To Reproduce

1. Rename a file and folder of package
   In my case it was
   android/app/src/main/java/za/co/io/reactnativekeystore/KeystoreModule.java android/app/src/main/java/za/co/io/reactnativekeystore/KeystorePackage.java
   and I renamed them to
   android/app/src/main/java/za/co/io/reactnativecrypto/CryptoModule.java android/app/src/main/java/za/co/io/reactnativecrypto/CryptoPackage.java
2. Restart VSCode
3. Language server fails to start throwing FileNotFoundException

Purging ~/Library/Application Support/Code/User/workspaceStorage and restarting VSCode solved the problem

Riproduci il malfunzionamento rinominando i file Java e il package da android/app/src/main/java/za/co/io/reactnativekeystore a reactnativecrypto, quindi riavviando VS Code. Esamina come l’estensione o il Language Server gestisce i file rinominati del workspace e lo stato del workspace memorizzato; il lavoro è completato quando il server si avvia dopo la rinomina senza richiedere l’eliminazione di workspaceStorage.
