error handling for local testnet REST query (#3739) 

When querying `ALTAIR_FORK_EPOCH` fails, the `launch_local_testnet`
script got stuck because comparing `CURRENT_FORK_EPOCH` against it
would keep failing with `[: : integer expression expected`.
Querying `ALTAIR_FORK_EPOCH` is now retried until a number is returned.
