`mint` function, after the mint happens.

This allows, for example, to check that any given condition is present after
the tokens have been minted.

If this function throws an exception, the asset will not be minted.

Throws if any extension of this function throws.

**Parameters**

* **account** — the account that has received the newly minted tokens
* **asset** — the asset that has been minted
* **amount** — the amount of tokens that have been minted
