Restore mouse_opacity for morpher ejected items (#3841)

# About the pull request

This PR simply restores the mouse_opacity setting for any item ejected
by the egg morpher. Normally /obj/item/storage/proc/_item_removal
restores this change, but the morpher is simply force moving items and
doesn't restore that to initial like removing from storage would
normally.

# Explain why it's good for the game

Fixes #3703 or at least should greatly mitigate it.
