build::default_label picked a new layer's label from its type alone
(comps Sandstone, images Lavender, ...), ignoring the label of the Project
item it was made from.
A layer made from an item (footage, comp, solid, 3D model) now copies the
item's label when it is created; every path that adds an item to a comp
(layer.addItem from the menus, Project panel, Timeline and viewer drops,
models, precomps, imports) builds its layer there. Layers keep their own
label when the item's changes later. Layers without an item keep the type
defaults.
