Jira Docker image with MySQL adds a schema name in dbconfig.xml breaking the connection to the database

Issue Summary

Running a docker image with MySQL, the dbconfig will have the schema name tag:

<schema-name>public</schema-name>

Environment

Docker Setup
Jira 8.4.2

Steps to Reproduce

1. Run docker with MySQL. Example:

   docker run -v jiraVolume:/var/atlassian/application-data/jira --name="jira" -d -p 8080:8080 -e "ATL_JDBC_URL=jdbc:mysql://192.168.1.0:3306/jiradb" -e "ATL_JDBC_USER=username" -e "ATL_JDBC_PASSWORD=password" -e "ATL_DB_DRIVER=com.mysql.jdbc.Driver" -e "ATL_DB_TYPE=mysql" atlassian/jira-software:8.4.2
   

2. Once this is up, check the dbconfig.xml

Expected Results

This should be as per Connecting Jira applications to MySQL 5.7 without a Schema Name.

Actual Results

<schema-name>public</schema-name>

Workaround

Manually remove this line.
