NPE in namespace transformation during the ivy:findrevision and ivy:resolve task execution

{code}
The same thing happens when calling ivy:resolve.
It has something to do with the way the ResolveEngine creates the DependencyDescriptor:
{code}
[...]
try {
return r.getDependency(new DefaultDependencyDescriptor(id, true), new ResolveData(this,
options, new ConfigurationResolveReport(this, md, "default", null, options)));
} catch (ParseException e) {
throw new RuntimeException("problem while parsing repository module descriptor for "
+ id + ": " + e, e);
}
[...]
{code}
that does not set the parent revision id of the descriptor (leaving it null). After some digging into the code I wrote a simple patch that fixes this issue:
{code}
