Stack overflow for mutually recursive type aliases

[rtfeldman]

To reproduce, add these type aliases to a roc program, or the repl:

Tool : [X, FromJob Job]
Job : [Job Tool (List Job)]

For example:

  The rockin’ roc repl
────────────────────────

Enter an expression, or :help, or :q to quit.

» Tool : [X, FromJob Job]
… Job : [Job Tool (List Job)]
… {}

thread 'main' has overflowed its stack
fatal runtime error: stack overflow
Abort trap: 6
