[Glitch] Fix timeline pagination in the WebUI

The `hasMore` property of timelines in redux store was set whenever an API
request returned only one page of results, *even* if the query only requested
newer statuses (using `since_id`), causing `hasMore` to be incorrectly set to
false whenever fetching new toots in a timeline, which happens each time
an account's timeline or media gallery is visited.
