Fix filters on timestamp attributes

[lauriejim]

⚠️ We have stopped merging PRs for now to the Strapi core.


The reason is that we are developing new architecture for the admin panel and for the plugins.

This new architecture will provide stability of the Strapi core as we approach the release of Beta.

We appreciate and welcome all your contributions, but until further notice, please do not submit a PR as it will not be merged.

Furthermore, you will have to rewrite it based on the new architecture.

Description:

Filter on timestamps attributes was not available.

Hello! Nop, but we will remove them because to many spec that are different for MySQL, Mongo...
So we plan to review the date layer soon. And when it will be done, we will add tests on data.
