ENH: do not include image metadata tables in catalog list

[bsipocz]

This PR makes the query behind list_catalogs more explicit to not return the image metadata tables by default. These tables are not suitable to be used for the spatial queries we have in query_region, etc.

This fully fixes #3330 and closes #3332
