The asserts were added in 45ab790e80
for better error detection.
The assert was happening because the duplicated layer
was referencing frames of the source layer by default,
causing the actual user counts of the drawings to be
in an invalid state (they they were getting fixed
after the call to `duplicate_layer`, but they could remain
invalid! ).
To fix this, we ensure that the user counts are correct
after calling `duplicate_layer`. New parameters are added
to allow duplicating the frames (with empty drawings) or
duplicating the frames and the drawings.
