Permission roles created for topics are inconsistent when created from UI

[Drifftr]

The permission role created for Topics are inconsistent when creating topics with the below mentioned steps

Steps.

1. Login to console and create a topic named Sports/Soccer
2. Create another topic named wso2.qa

Issue - The two role names that are created are inconsistent (refer pic1). Further if a subtopic is created by a jms client it uses the hyphen to distinguish role names.

With reference to : https://wso2.org/jira/browse/MB-1461
