CamtrapDP datasets replacing DWCA datasets cannot be crawled

[MattBlissett]

The crawler-dwca-validator runs after the CamtrapDP conversion, and unpacks the old DWCA replacing the newly converted one.

A similar problem might cause new CamtrapDP datasets to fail.

This is currently a blocker for 3 (new) datasets @jevansbio has published:

Pilot 1: https://www.gbif.org/dataset/74196cd9-7ebc-4b20-bc27-3c2d22e31ed7
Pilot 2: https://www.gbif.org/dataset/f9ba3c2e-0636-4f66-a4b5-b8c138046e9e
Pilot 3: https://www.gbif.org/dataset/bc0acb9a-131f-4085-93ae-a46e08564ac5

Is it possible to enable processing for new Camtrap DP datasets (and maybe also the ones replacing an original DwC-A dataset) even if the metadata is minimal?
