trying to fetch lastjobsummaries with count and spiderid does not work

[pawelmhm]

following call

summaries = project.spiders.lastjobsummary(count=10, spiderid="123")

always returns just one jobsummary for spider with id, not 10 summaries. I know this call is called lastjobsummary not last10jobssummary but it could be nice to fetch couple of most recent job summaries for a spider and seems like there is no easy way to do this now, or am I missing something?
