Refresh Workspace does not work without debug plugin

[Lucas Alber]

Server-Log:

:: --> jdtls workspace/executeCommand(10): {'command': 'vscode.java.resolveBuildFiles'}
:: <~~ jdtls 10: {'message': 'No delegateCommandHandler for vscode.java.resolveBuildFiles', 'code': -32601}

Maybe the LSP-jdtls should always ship with the debug plugin included?
