OpenTelemetry log error occurred when dropping the old log_provider, and create a new one

[vincenzopalazzo]

I have the following code

use clap::Parser;

use opentelemetry_log::Opentelemetry;

#[derive(Debug, Parser)]
#[clap(name = "opentelemetry.rs")]
pub struct Args {
    #[clap(short, long, value_parser)]
    pub url: String,
    #[clap(short, long, value_parser)]
    pub message: String,
    #[clap(short, long)]
    pub level: String,
}

// the async main is not required by our application
// but the opentelemetry app is requiring to be
// in an async context, so we use this
#[tokio::main]
async fn main() -> anyhow::Result<()> {
    let args = Args::parse();
    let url = args.url;

    let mut manager = Opentelemetry::new();
    manager.init_log("example", &args.level, &url)?;

    match args.level.as_str() {
        "info" => log::info!("{}", args.message),
        "debug" => log::debug!("{}", args.message),
        _ => anyhow::bail!("level `{}` not found", args.level),
    }
    drop(manager);

    let mut manager = Opentelemetry::new();
    manager.init_log("foo", &args.level, &url)?;

    match args.level.as_str() {
        "info" => log::info!("{}", args.message),
        "debug" => log::debug!("{}", args.message),
        _ => anyhow::bail!("level `{}` not found", args.level),
    }
    Ok(())
}

Where drop(mamager) is just https://github.com/vincenzopalazzo/opentelemetry-log/blob/main/src/lib.rs#L92

When dropping I get the following error

OpenTelemetry log error occurred. cannot send message to batch processor as the channel is closed Error: attempted to set a logger after the logging system was already initialized

A minimal reproducible example of the problem is vincenzopalazzo/opentelemetry-log#3

The use case of this is: Immagine that you have a kind of identifier (user identifier) and you need to switch when inside the application it is switching the profile. I am doing something wrong? or this is a real bug?
