Include correct limits in LimitOffsetPagination link urls

[strixcuriosus]

For LimitOffsetPagination, if the limit from the query param is invalid or greater than the max_limit, then the previous and next links should contain the actual limit being used instead of the originally requested limit.

Examples:

• with a default_limit set, a request to http://testserver/?limit=hello

# instead of keeping the invalid limit in the url
url = 'http://testserver/?limit=hello&offset{0}'.format(default_limit)
# should provide a next link with the default_limit in the url
url = 'http://testserver/?limit={0}&offset={1}'.format(default_limit, default_limit)

• similarly, with a max_limit set to 10, a request to http://testserver/?limit=100 should provide a next link with url http://testserver/?limit=10&offset=10 instead of http://testserver/?limit=100&offset=10

Yup, looks good. Nice catch.
