When specifying an external DB that has a semicolon within the URL, startup of the repo container fails.

Steps to Reproduce
1. Follow github docs to deploy chart version 5.0.0 with external database. https://github.com/Alfresco/acs-deployment/blob/master/docs/helm/examples/with-aws-services.md#deploy
2. Specify a SQLServer DB with semicolons contained in the URL, e.g.

Expected Behavior
Repo container successfully starts and connects to the SQLServer DB
