db:create should bypass the 'database' option

## Current behavior

My `database.json` file:

```database.json
{
"dev": {
"driver": "mysql",
"user": "root",
"password": "root",
"database": "some_database_that_doesnt_exist_yet"
}
}
```
The command:

`db-migrate db:create some_database_that_doesnt_exist_yet`

The result:

```
[ERROR] AssertionError [ERR_ASSERTION]: ifError got unwanted exception: ER_BAD_DB_ERROR: Unknown database 'some_database_that_doesnt_exist_yet'
...
```

## Expected behavior

Create the db even if the database option exists, esp. because I tend to create the db that's mentioned in `database.json`.

## Minimal reproduction of the problem with instructions

See current behavior.

## What is the motivation / use case for changing the behavior?

I write the database name that I plan to use, 'my_db', in the config. I run `db-migrate db:create my_db`. It errors. I cut the database option out. I rerun the `db-migrate db:create my_db` command. It creates the db. I paste the database option back in. It works.

The middle two steps shouldn't be necessary, because no database-specific queries are involved. It should just create the db.

## Environment

db-migrate version: 0.11.11

plugins with versions: ?

db-migrate driver with versions: db-migrate-mysql@2.1.1
