Project tags lost on pagination

[adammcmaster]

This is probably a wider issue affecting the ResultPaginator in other cases, but unfortunately I don't have time to debug it any further myself.

When paging through projects, the client drops the tags argument when it requests subsequent pages:

import os

os.environ['PANOPTES_DEBUG'] = 'True'

from panoptes_client import Project

ps = Project.where(tags='astronomy', launch_approved='true')
for p in ps:
    print(p.display_name)
