remove it.

File manager main: use readyState "loading" DOMContentLoaded

main_scripts.js has a defer attribute: add DOMContentLoaded if needed,
ie., only if the document is loading. And modernize the remaining code
while here.

Send util.testSendMessage('ready') at Files app start-up

CL:1237801 removed this start-up message, but it was being used in the
ui/views/select_file_dialog_extension_browsertest.cc tests. These file
extension dialog browser tests didn't complain about the message being
removed because the they're DISABLED on Chrome OS ¯\(ツ)/¯

We should get those test running again, which will be the subject of a
of a new testing bug. For now, recover the 'ready' start-up message.
