Using factories by morph name

[Prashank25]

Hello,

this is the PR for issue #50, I got no response on the issue so I figured I might as well try a PR directly.

This PR adds support for using factories by Eloquent model morph name.

cy.create('App\\Models\\User', { email: 'test@example.com' });

can be a little more simplified and more straightforward to type

cy.create('user', { email: 'test@example.com' });

cy.create({
    model: 'user',
    attributes: { email: 'test@example.com' },
    count: 10
})

Feel free to close it if it's not something you want in the package.

Thank you!
