Scratch 3 should allow sprites named "stage"

[kchadha]

In both the 2.0 and 3.0 editors, you can create a sprite named 'stage'. Saving and loading this project in 3.0 does not work. This is the root cause of the not being able to remix chess-escape project.

E.g. saving and loading this project in 3.0 does not work:
