Incomplete decorator cannot be put after a metadata decorator

[jmvrbanac]

If the Incomplete decorator is at the end of the execution chain

    @incomplete
    @metadata(category='positive')
    def can_retrieve(self):
        pass

It results in output like:

    --snip--
    ∟ DECORATOR ONCALL
    --snip--

When It really should look like:

    --snip--
    ∟ can retrieve (incomplete)
    --snip--
