Add @localhost to last MySQL command

[MaxGabriel]

It's been a long time since I remembered MySQL user naming convention stuff, but, just empirically I get the following error following the README instructions:

mysql -u root

mysql> GRANT ALL ON esqutest.* TO 'travis';
ERROR 1410 (42000): You are not allowed to create a user with GRANT
mysql> GRANT ALL ON esqutest.* TO 'travis'@'localhost';
Query OK, 0 rows affected (0.00 sec)

MySQL version:

~/D/C/H/esqueleto> mysql --version                                                                                                                                                                                                                                                                                                                                  12:38:37
