fix the bug findAndCountAll not working on postgresql.

copy where array, avoid changed by internal.

Could you please provide a test case that needs this? This should be fixed by #884 - which is in master, but not npm, so you might need to update to that

[hackwaly]

I'm sorry for my careless commits.

[janmeier]

Thanks for the test :)

For some reason travis has not run your commits so I just tried them locally. The same problem is also present for other dialects, so fixing it for postgres only is not enough. I think you should use the optClone method in the count method like ion #884

[hackwaly]

That's just I want to say.
but, I think it's not best just wrap the caller functions which pass options parameter. Some internal functions has side effect. They may break other internal functions, not only the count or find etc.
These function should not have side effect, they are not control flow or context aware functions.
What do you think about?

[hackwaly]

Is this ok?

[janmeier]

Jup, very o.k. This is actually better than the fix in 884 so I removed that again since your PR covers all cases
