[Bug] Broken collections support

[Silicon7921]

Describe the bug
"fav status -a" command shows collections that is subscribed, BUT ALSO those have been unsubscribed.

To Reproduce

1. subscribe a collection on bilibili and find its ID in the webpage URL, like "collectiondetail?sid=2800646". write it down.
2. perform "fav status -a", notice that the ID appears in the command output as expected.
3. unsubscribe the collection subscribed before.
4. perform "fav status -a" again. that ID don't disappear (it should disappear, since I have unsubed it) .

Expected behavior
Any ID of unsubscribed collections don't appear in the output of "status -a"

Screenshots

any unsubscribed collections are marked. the "count" is completely wrong. I dont have so many collections sub.

Information (please complete the following information):
Windows 11 build 22621
fav version 0.2.29 (latest)

Additional context
If this is a BUG, that means "collection support" cannot handle unsubscribed collections and still display them.
By the way, how can I track a collection? or it have not been realized?

I will add the --prune flag to fetch like what git fetch does once I'm available.
