While creating service, ranger logs show error if service name does not have underscore ('_') in it.

When we create a service, a linked tag service also gets created for the same. While doing so, ranger generates a name for the tag service based on the service name. In this, ranger replaces word after the last underscore with 'tag'. If the name does not contain any underscore, it returns null. Due to this, ranger tries to create a tag service with name null. This causes errors and service creation takes lot of time because of this.

Following errors are seen in logs
