If an empty namespace is given, it is deduced automatically. We assume that a single probe with the given name exists. If multiple probes having the same name but different namespaces are matched, no probes are attached to and the user is told to use an explicit wildcard for the namespace.
This solves dicrepancy between the tests (which treat an empty namespace as a wildcard) and the reference guide (which says that an empty namespace is replaced by the binary name).
Resolves #1469 and fixes #1466.
