Suppose that rather than use base_prefix to change the default of "mobile_base", a
user wishes to entirely remove the base prefix. If the param
base_prefix is set to the empty string, then the topic names
would become absolute, i.e., would begin with "/". This changeset
ensures that they remain relative in this case.
The motivating use-case is spawning multiple instances of the Kobuki model, each with a unique namespace, while trying to keep topic names short.
