Should be able to "Write Contract" if no abi exists #144
Description
When we have the ABI of the contract saved, we can click "Write Contract" on the transaction, and it redirects us to the contract tab on the address page, prefilled with the function and calldata parameters.
However, if the ABI is not available, this functionality currently doesn't work. We should still be able to reproduce the transaction call even without the ABI. This requires changes to the Contract tab on the address page, and the an UI that can correctly reflect this case.
