add bats test for binary string encoded to utf8

[jennifersp]

Depends on dolthub/go-mysql-server#1583
DataGrip sets the character_set_results system variable to utf8, which raw binary strings cannot be encoded into. MySQL returns binary type strings in hex format.

Not sure this needs to be in server mode.

Test looks good. Tim has a good comment about whether we could just use dolt sql instead of going through a sql-server. From what we just discussed, it seems like it's true that dolt sql should be enough to trigger the issue? Could you test that out and confirm?
