    extension-tool: Don't treat missing .js handler as error
    
    After creating a new extension, we try to open the main source
    file with the default handler, which fails when there is none.
    
    But given that the extension was created successfully, don't treat
    a missing handler as failure, and print the path to the new extension
    instead.
