Fixed tests for fe594950c5

We actually expect an extra space. The previous build failed because a test is issued for location='', which indeed results in 2 spaces between the architecture specification and the release. According to the sources.list man page a location is always required though (unlike the missing/empty location in the :default_params of the source_spec test).
