Enum based filters do not take effect when exporting data

[sparkhi]

The filters, which are internally based on Enums (i.e. RESOURCE_TYPE, IDENTIFICATION_METHOD and JOB_STATUS) fail to be applied when exporting the data.

Steps to reproduce:

1. Launch Droid GUI
2. Add some folder, choose a folder which has files as well as folders underneath
3. Click start and run the identification
4. Click on Filter and add a filter (e.g. RESOURCE_TYPE Any of FILE)
5. Run an export
6. You will notice that the export is totally blank because none of the records satisfy the filter criteria. BUG!! 🐛

Observed as far back as v6.6.1, It worked fine in v6.5

Hint: I believe the comparison between an Enum and an Integer value corresponding to its Ordinal is failing
