Multiple plugins inside same file not registered

[JSCU-CNI]

Given the following setup:

dissect/target/plugins/apps/nsexample/
├── foobar.py
├── __init__.py
└── nsexample.py

*nsexample/nsexample.py*

from dissect.target.plugin import NamespacePlugin


class ExampleNamespacePlugin(NamespacePlugin):
    """example namespace plugin"""
    __namespace__ = "nsexample"

*nsexample/foobar.py*

from typing import Iterator
from dissect.target.plugin import export
from dissect.target.plugins.apps.nsexample.nsexample import ExampleNamespacePlugin


class FooPlugin(ExampleNamespacePlugin):
    """Foo plugin."""

    __namespace__ = "foo"

    @export(output="yield")
    def hello(self) -> Iterator[str]:
        """hello from foo.example"""
        yield "hello from foo.example"


class BarPlugin(ExampleNamespacePlugin):
    """Bar plugin."""

    __namespace__ = "bar"

    @export(output="yield")
    def hello(self) -> Iterator[str]:
        """hello from bar.example"""
        yield "hello from bar.example"

We would expect both foo.hello and bar.hello to be registered as plugins. However it seems only bar.hello is registered. the namespace plugin nsexample.hello does seem to pick up foo.hello.

$ target-query -l | grep hello
bar.hello - hello from bar.example (output: lines)
nsexample.hello - Return hello for: foo,bar (output: records)

I wonder if #763 already has any impact on this. At least it will be a requirement before touching this.

I'll try and rebase that soon.
