No, the timeline we've seen since that "glitch" moment that happened right as Asriel fell asleep and dreamed of his conversation with Flowey is timeline 2, a timeline that branched off from the initial caused by Chara entering an old point in the timeline and placing the Locket on the drawer. The current situation with the timeline has nothing to do with mere "relics" existing from the "old timeline," as we can see that even Frisk existed in this point in time in timeline 2, only circumvented by the fact that no one remembers him. What I mean by that is, Frisk still exists up until the ending of My Promise, but no one has any recollection of him up until that point. Sans doesn't technically remember him either, he just notices traces of someone missing, but he can't put his mind on who that person is. So, the "relics from the first timeline" that you speak of don't come from the timeline where only one Locket remains, but instead come from this second timeline that branched off from the initial one.

In conclusion (or just me repeating the main point): Frisk at some point existed in the second timeline, but stopped existing when he replaced himself with Chara. Sure, he exists in the timeline with only a single Locket as well, but the same thing happens there. He goes to the void, encounters Chara there, then replaces himself with them, and gets erased from the timeline. And then the bad thing that happens in the first timeline happens as you'd expect, and Chara has to enter the old point in the timeline and cause it to split to create a better outcome, timeline 2. So no, the timeline didn't get erased after My Promise, because what we've seen up until that one aforementioned moment in LOVE Part 2 is timeline 2, which is unlikely to be erased. You're talking about the version of those events that existed in the timeline 1 versions of the episodes since that branch-off point in the timeline.
