Group notes by year after import is buggy

[nicosomb]

What happened?

I have a NaN date when I import old notes (created in 2018) and when I want to group notes by year.

see #4730

Steps to reproduce the problem

Import old notes (with a creation date in 2018, it also occurs with a recent date in fact). Try to group your notes by creation year. You've got a NaN date.

I've got the same problem, but weirdly "group by week" works without problems

Group by week

Group by month

Group by year

Note Properties All notes have in the properties the proper created at and edited at

Same exact problem after importing from Markdown with created_at and updated_at frontmatter
