Remove hard coded DOI data for data collection ESRF-DC-142893590 and ESRF-DC-14291526
These 2 DOI were hard coded end of december 2018 when datacite was not operational. Since then we have implemented another solution which takes data from ICAT when datacite does not work.
- Remove the hardcoded doi data.
- Make sure the DOI landing page for these 2 doi is rendered when datacite does not work. (using ICAT)
