[BUGFIX beta] prevent calls to store.query leaking

Although the result from `store.query` is intended to never be re-used
as we delegate to the server for the truth of a query, the user still
needs an escape hatch to destroy these AdapterPopulatedRecordArrays
created by query in order to prevent excessive memory.

Before, calling `destroy` on an AdapterPopulatedRecordArray (the type
returned from store.query), the logic in
RecordArrayManager#unregisterRecordArray did not account for adapter
populated record arrays resulting in a leak.

This commit changes the logic to search for the array in the
RecordArrayManager's AdapterPopulatedRecordArray collection when
unregistering a record array.

Fixes #4041
