Remote Crowd directory connection URL cannot contain "/services"

RemoteCrowdDirectory#getClientProperties() creates ClientProperties with crowd.server.url property instead of crowd.base.url property. crowd.server.url property is expected to contain a valid SOAP URL. Valid SOAP URLs end with "/services" or "/services/". ClientPropertiesImpl#generateBaseURL(java.util.Properties) tries to generate a base URL of crowd.server.url property by looking for "/services" starting from the end, and misbehaves if the SOAP url is not valid but contains "/services".

Both RemoteCrowdDirectory#getClientProperties() and ClientPropertiesImpl#generateBaseURL(java.util.Properties) need to be fixed.
