Error if the plugin `nvim-web-devicons` is not installed

[dhruvmanila]

As per the installation instruction, it is fine to not install nvim-web-devicons but then the plugin fails to load due to this line.

There is this option: override_nvim_web_devicons but that makes sense if nvim-web-devicons are installed. It should have no effect if the plugin is not installed in the first place.

@dhruvmanila do you have any progress on this case? I wonder where you have defined override_nvim_web_devicons exactly as well. Thanks.
