Transactions - kill the old "show all" code pathways

Summary: we still need to be pager-sensitive, but otherwise this "show all" stuff is dead, dead dead...! Ref T4712. I think we can close the book on T4712 with one more diff to clean up the array_reverse / reverse paging stuff? That diff is probably a bit tricky as it involes auditing every TransactionQuery callsite...

Test Plan: viewed a task with a lot of transactions. clicked "show older" and it worked!

Transactions - fix pagination bug

Summary: Fixes T6694. Ref T4712. Turns out the logic here was slightly incorrect; we don't want to use the id of the last thing we hid but rather the first thing we show. I had garbage test data ("asdsadsadsa", etc) I guess so I didn't notice this.

Test Plan: made a new task where user a and user b alternated 3 comments each, cooperatively numbering them from 1 - 20. as both users, showed older transactions. pre-patch the issue described in T6694 occurred and post patch I saw the entire counting sequence.

Transactions - fix bug in differential where older inlines weren't appearing

Summary: Fixes T6699. We need to "loadInlineComments" consistently, though for an unexpected reason - this mutates the $changesets to include all $changesets that have an associated inline comment, which is necessary to make them render properly.

Test Plan: Took a diff with inline comments and updated it, noting the inline comments disappeared. applied this patch and the inlines reappeared.
