Knesset Document Committee Session API - invalid data - duplicate ID

### reproduction
* http://knesset.gov.il/Odata/ParliamentInfo.svc/KNS_DocumentCommitteeSession?$skiptoken=187000L
* look for id KNS_DocumentCommitteeSession(187001L)
* try to get the details for this id - http://knesset.gov.il/Odata/ParliamentInfo.svc/KNS_DocumentCommitteeSession(187001L)

#### expected
* a single entry for id KNS_DocumentCommitteeSession(187001L)
* should be able to get the details from the ID

#### actual
* two entries with the same id - KNS_DocumentCommitteeSession(187001L)
* getting error when trying to fetch this ID

Start by querying the KNS_DocumentCommitteeSession endpoint with $skiptoken=187000L and compare the two entries for KNS_DocumentCommitteeSession(187001L). Then test the item URL for that ID; done means the collection contains one entry and the ID URL returns its details without an error.
