Fix query result lazy loading

[andrykonchin]

Old behaviour of Model.where({}).all:

• load lazily if user specified batch size
• load all collection into memory otherwise

Proposed behaviour - always return lazy evaluated collection

It means Model.where({}).all returns Enumerator instead of Array. If you need Array interface you have to convert collection to Array manually with to_a method call

@pboling @richardhsu I propose to not merge open PRs untill new release. I beleive we should release new version with bug fixes ASAP

[pboling]

I agree, this will be merged after the new release.

I have created a 1-3-stable branch for maintenance of the old version (current release), so now we can start working on the next version, which I expect will have major breaking changes, and so should be version 2.0.0.
