[bugfix] ensure timeline limit query is respected (#4141)

# Description

Fixes a bug in the new timeline code in which the limit query parameter wasn't always being fulfilled, in which case some clients like Tusky would then assume it didn't need to add a "load more" placeholder view even when there were more statuses to be loaded. This also fiddles around a bit in the logging middleware handler to add some more code comments, and add logging of full request URIs when it is safe to do so.
