Extensions must be present and must be at least 2 characters long

Hello,

It affects docs but maybe other modules.

What steps will reproduce the problem?
1. touch /tmp/try
2. google docs upload --src /tmp/try --title 'try'
Traceback (most recent call last):
  File "/usr/bin/google", line 849, in <module>
    main()
  File "/usr/bin/google", line 835, in main
    run_once(options, args)
  File "/usr/bin/google", line 633, in run_once
    raise run_error
AttributeError: 'NoneType' object has no attribute 'upper'

1. touch /tmp/try.xx
2. google docs upload --src /tmp/try.xx --title 'try'
No supported filetype found for extension xx
Loading /tmp/try.xx
Upload success! Direct link: xxxxxxxxxxxxxxxxxxx
