Being able to assert only "/" on a GET HTTP call

[Z31ADHER]

Currently, it is impossible to assert the root of an API using tzatziki. The following will return an error on uri format.

The steps  :

        When we get "/"
        Then we receive a status OK_200 and only:
"""
// your body here
"""

Stacktrace of the error

java.lang.AssertionError: invalid uri: /
	at org.junit.Assert.fail(Assert.java:89)

Seems like there is a constraint on having at least one character after the root in the RegEx for the URI pattern
