### Apache Airflow version

At airflow log view (DAG -> task -> log) of `EmptyOperator`, an error shows
in window:
```
*** Could not read served logs: Request URL is missing an 'http://' or
'https://' protocol.
```
Full trace in console:

### What you think should happen instead
Old version of airflow (I tested 2.6.0), log view of `EmptyOperator` will
show noting,
I'm not sure this behavior is documented, but It caused confusion for me at
least.
### How to reproduce
1. I use python venv with whl in GitHub releases for installation.
2. Run `airflow standalone` for development deploy, I also disable
load_examples.
3. Using `EmptyOperator` example like below, I also disable catchup of DAG:
```Python
import datetime
from airflow import DAG
from airflow.operators.empty import EmptyOperator
with DAG(
dag_id="demo",
start_date=datetime.datetime(2021, 1, 1),
schedule="@daily",
catchup=False,
):
EmptyOperator(task_id="demo")
```
4. Enable the DAG in airflow webserver, wait it for a run.
5. Navigate to demo dag, demo task; press log view at toolbar.
### Operating System
NixOS 23.05 (Stoat)
### Versions of Apache Airflow Providers
```
apache-airflow-providers-common-sql==1.7.1
apache-airflow-providers-ftp==3.5.1
apache-airflow-providers-http==4.5.1
apache-airflow-providers-imap==3.3.1
apache-airflow-providers-sqlite==3.4.3
```
### Deployment
Virtualenv installation
### Deployment details
Our enterprise internal deployment using modified docker-compose, version
2.7.0 shows the same issue.
But our old 2.5.2 venv deployment works fine. `EmptyOperator` shows nothing
as normal.
