qmllint: Properly handle JavaScript functions with variable arguments

Previously calling a JavaScript function with variable arguments could
cause the linting process to error out because of a lack of matching
function arguments.

This is now handled by defaulting to a JavaScript method if no matching
function signature can be found.
