test: firmware uploadInProgress: writeMeta typo

Typo was that it was originally titled to return success, then
implemented, and really the success is a nice failure.  Read() returns
no data on failure instead of something useful.  writeMeta actually
returns a boolean on failure.  Therefore, this test returns failure.
However, it's returning failure because it doesn't have a data handler.
There is another test already that handles that.
