plugins/configs/statusline: Fix git branch not appearing without opening files

* the default provider given by feline uses gitsigns which only updates when a file is opened

* code taken from: https://github.com/hoob3rt/lualine.nvim/blob/master/lua/lualine/components/branch.lua

* use gitsigns var when available
