Fix collision of Elastica\Type and Elastica\Filter\Type in \Elastica\Filter\Ids

Noticed that when using Elastica\Filter\Type this error shows: Cannot use Elastica\Type as Type because the name is already in use.

This fixes the collision in Elastica\Filter\Ids between Elastica\Type and Elastica\Filter\Type

If it's better that we switch to Elastica\Filter insted of use as ElasticaFilter, tell me and I'll resubmit the PR.

Cheers
