Test file uploads to the test wiki

There is
https://test.wikipedia.org/wiki/Main_Page
for specifically bot testing purposes.

So we should be testing the fix to #62 #63.

Once we have a few useful uploads there, I will start the bot request #67 and on that basis, the unblock request #66 is hopefully getting in reach of being granted.
