[Bug] execution_count is missing

[tzachar]

Describe the bug

This is what I get on save:

To Reproduce Steps to reproduce the behavior: Start magma, execute a cell and try to save the buffer

Expected behavior no bug...

Ah, that's what I get for not having setup any form of static typing. Sorry for the inconvenience.

Fixed in 0ab5ef297bf98d69f03bb069533444c14cd53383; however, I noticed that the outputs don't seem to be brought in on :MagmaLoad, but it looks like that was already the case for a little while... nevertheless, I'm looking into it.
