The response of prop=imageinfo is now an array instead of an object.
Therefor it is not needed to interate over the elements anymore.
The array contains exact one element if one title is used in the query.
The function getNormalizedTitle not needed anymore because the
requested title is always the first element of the array.

* Removed deprecated testCount, which is no longer supported in this way.
It's only useful when wanting to explicitly expect 0 assertions (normally
considered an error).
* Replaced use of testCount = 0, with assert.expect( 0 ).
