chore: Added cross contract tests

[ChaoticTempest]

Added this specific test case where creating a top level account from a cross contract call should fail for a name that is too short in length

[itegulov]

That's an interesting behavior. Is there a way we can improve the error message from the SDK side?

[austinabell]

Where is this behaviour documented? This seems very strange and want to understand it before we create a test case around it specifically

@austinabell you can find it here: https://docs.near.org/docs/concepts/account

To allow for fair access to them, the top-level account names that are shorter than MIN_ALLOWED_TOP_LEVEL_ACCOUNT_LENGTH characters (32 at time of writing) will be auctioned off.

Specifically, only REGISTRAR_ACCOUNT_ID account can create new top-level accounts that are shorter than MIN_ALLOWED_TOP_LEVEL_ACCOUNT_LENGTH characters

@itegulov think it would require a protocol change since the host functions don't supply an error message when a Promise fails
