Initialize name property for ImagePlus outputs

[imagejan]

When you define:

@Parameter (type = ItemIO.OUTPUT)
private ImagePlus imp;

in an ImageJ2 command, the output Img in KNIME should get its name attribute populated from imp.getTitle(). Currently, it is always null which can lead to unexpected errors downstream of nodes with this output.
I assume this change would need to go somewhere into these lines:

knip-imagej2/org.knime.knip.imagej2.core/src/org/knime/knip/imagej2/core/adapter/impl/ImagePlusOutputAdapter.java

Lines 113 to 118 in 63858c2

	ImgPlusCell output = null;
	try {
	output = factory.createCell(new ImgPlus(image));
	} catch (final IOException e) {
	e.printStackTrace();
	}

EDIT: the output image also contains additional dimensions of length 1 and labelled Unknown. It would be nice to keep the dimensions from the ImagePlus, or at least clean the dimensions of length 1.
