Change type of `lastPriceToken` from string to Token

On Order , lastPriceToken should be Token

I changed it back to string as it was causing problems: https://github.com/oceanprotocol/ocean-subgraph/pull/477

Will do another PR for this with more testing.

we need to make sure the Token exists, so when assigning a value to lastPriceToken we need to do a getToken. This function automatically created the token if not existing.

From what I can see we already call getToken() before updating the lastPriceToken in handleOrderStarted. https://github.com/oceanprotocol/ocean-subgraph/blob/5da91c228211544fc76f26e3cb7df1884a274b21/src/mappings/erc20Templates.ts#L39

Are you referring to a different function?

[mihaisc]

That should be it. Then we need to debug what is not working.

Why only on Order? lastPriceToken in Token is string, I'm not sure why they would be different?

[mihaisc]

They shouldn't , we just missed it
