bug: Legacy thread show on top of New thread

[LazyYuuki]

Version: 0.6.4

Describe the Bug

When migrating from Legacy version of Jan to newer version, some of the Legacy thread get put on top of the more recent thread.

• New Chat -> doesn't show up at top of convo list
• Top of Convo List is a bunch of legacy threads

Could be caused by the fact that the older legacy thread does not have datetime field in it.

Steps to Reproduce

1. Migrate from legacy version of Jan to v0.6.4
2. Open up thread, all the Legacy thread got put on top instead of in chronological order
