Previously, internal links of node are only shown when the link is muted AND when the corresponding output is linked to something else. I can't think of any reason for why it's important whether the output is linked or not. It seems showing the internal link is always useful. This patch makes it so that all internal links are always shown when a node is muted, regardless of whether the corresponding output socket is linked or not.
