Subject: [PATCH] fix(tabpages): renaming bug on reopened tab (#877)

vim.fn.tabpagenr gets the tab number but api.nvim_tabpage_set_var
expects tab id, meaning the tab rename would fail if a tab was closed
and reopened. This change passes 0 into api.nvim_tabpage_set_var
which will use the current focused tab without needing to retrieve
the id.
