@webdoc/parser `1.6.0` crashes when mangling a method with no parameter

When @webdoc/parser parses a method that has no parameters, it crashes with the following error:

(node:4199) UnhandledPromiseRejectionWarning: TypeError: Cannot read property 'map' of undefined

The mangled() function doesn't check if params is defined, it should probably return something like ${doc.type}:${doc.name} or ${doc.type}:${doc.name}:undefined when that is the case:
