get_or_create_detector_by_name doesn't handle special characters #194

If you run the following
a = gl.get_or_create_detector("det", "query") b = gl.get_or_create_detector("det+", "query")
then a and b will reference the same detector.
This is particularly perplexing if you use datetime to generate a unique name and the string representation ends with timezone information like +00:00
