solana-ibc: use a proper timestamp in mock headers (#134)

The timestamp default to None while setting up mock headers in the tests. Since they are not set ( None ), it fails while comparing the current timestamp. So using a value instead would solve it. The value has to be less than the current timestamp.

* use a timestamp value instead of None

* fmt

* fix imports
