The Recently Viewed entities API to be filtered by owner

[jachro]

Our UI seems to be interested in having a filter to reduce the list of recently viewed entities just to the ones owned by the caller.

Acceptance criteria:

• Add a new owned valueless query parameter that would shorten the list of results just to the entities owned by the caller
  • The matching to be done on the GL id exchanged with the access token coming from the request
  • The owner of an entity to be a project member having the given GL id and Owner role.
