[Bug]: error when closing last tab

### Is there an existing issue for this?

- [x] I have searched the existing issues

### What happened?

When using bufferline in `mode='tabs'`, closing the last tab (with the x-icon on the tab) shows an error message. (Because the last tab page cant be closed with `tabclose`)

### What did you expect to happen?

I expected to have an empty/new buffer left (and close all my other buffers from that tab).
OR
To not see an x icon at all.

### Config

With lazyvim:
```lua
return {
'akinsho/bufferline.nvim',
version = "*",
dependencies = {
'nvim-tree/nvim-web-devicons',
},
config = function()
vim.opt.termguicolors = true
require("bufferline").setup {
options = {
mode = 'tabs'
}
}
end,
}
```

### Additional Information

The error message:
```lua
