Deleted remotes are still listed despite not being present in local .git folder

**Describe the bug**
When looking at the remotes list, it shows a lot of remotes that I have deleted. When looking at `.git/refs/remotes` the deleted remotes are indeed not present so I don't know why it lists all those remotes.

**To Reproduce**
I'm not entirely sure of an easy way to reproduce this. I'm trying to transition from gitkraken to lazygit and the remotes were deleted using gitkraken so I'm not sure what the exact steps would be.

**Expected behavior**
Shows only the list of remotes that still exist locally.

**Screenshots**
left-side is the .git/refs/remotes folder and right-side is the lazygit remotes view


All the remotes with `0 branches` are remotes that I deleted over many years. I tried using the delete function of lazygit but all I get is an error saying the remote doesn't exist.
