search_issues() result has totalCount maxed out to 1000

The paginated list returned from a search_issues() will report a totalCount that maxes out to 1000 when a search query results in more than 1000 items. The totalCount() method in PaginatedList() will get headers and data from result of a requester.requestJsonAndCheck() using the first URL. The logic then tests to see if 'link' is not in headers which in my case there is a 'link' so it falls to the else side and parses the lastUrl line for 'page' which is 1000.

Problem though is that in my search, the original 'data' structure has a valid 'total_count' field of 3041 so I'm not sure why the logic tries to derive something from the lastUrl which is generating an incorrect value?

And if I iterate through the PaginatedList returned I count only 1020 items so I'm not able to iterate through all 3041 items. Note that I put rate limiting code in the iteration loop to sleep checking on get_rate_limit().search.remaining to go nonzero.
