Issue Summary

Crowd allows to persist base URLs both with and without a trailing slash, as opposed to other Atlassian products. SAL's ApplicationProperties will then directly return the persisted base URL value. This behavior is not in-line with other Atlassian products which typically remove the trailing slash from the base URL - either before persisting or before returning the API response. As a result cross-product plugins may rely on the assumption that the base url will always lack a trailing slash.

Steps to Reproduce

1. Configure a base URL with a trailing slash in Crowd
2. Retrieve the base URL with `com.atlassian.sal.api.ApplicationProperties#getBaseUrl(UrlMode.CANONICAL)`

Expected Results

Base URL is returned without a trailing slash.

Actual Results

Base URL is returned with a trailing slash.

Workaround

Save the base URL without a trailing slash.
