Exact filter on admin table availability column errors #1719
Description
If you try and type an exact filter in the admin download status table in the Availability column, it errors. Patrick has an example curl request that works:
curl 'https://icat.diamond.ac.uk/topcat/admin/downloads?sessionId=mySessionId&facilityName=DLS&queryOffset=WHERE+download.facilityName+%3D+%27DLS%27+AND+download.status+%3D+org.icatproject.topcat.domain.DownloadStatus.RESTORING+AND+download.isDeleted+%3D+%27false%27+ORDER+BY+download.createdAt+desc%2C+download.id+ASC+LIMIT+0%2C+50'
This requires using the full path for the enum. So need to investigate whether this is strictly needed and if it is then need to have special handling for the status enum
