[Bug] Nodes are reloaded twice

Description

Meshroom/meshroom/ui/reconstruction.py

Lines 441 to 444 in e704e5b

	for plugin in meshroom.core.pluginManager.getPlugins().values():
	for node in plugin.nodes.values():
	if node.reload():
	nodeTypes.append(node.nodeDescriptor.__name__)

For some reason when I trigger the plugins hot-reload they are reloaded twice.
It doesn't seem to depend on the number of node instance

Reproduction steps

1. Create a dummy plugin, for example :

class TestNode(desc.Node):

    print("Load TestNode")

    category = 'TestPlugin'
    documentation = """Test node"""
    
    size = desc.StaticNodeSize(1)
    parallelization = None

    inputs = [
        desc.File(
            name='inputA',
            label='input',
            description='',
            value='',
        ),
        desc.File(
            name='inputB',
            label='input',
            description='',
            value='',
        )
    ]

    outputs = [
        desc.File(
            name='outputFolder',
            label='outputFolder',
            description='outputFolder',
            value="{nodeCacheFolder}",
            group='',
        ),
    ]

    def processChunk(self, chunk):
        pass

2. Launch meshroom
3. Change the code of the plugin (e.g. remove inputB)
4. Trigger the hot-reload

5. You can see that TestNode is reloaded twice
