Fix incorrect selection flags for ec serializer.

Browse Source 
Fixes #12630

ec_import requires domain parameters to be part of the selection.
The public and private serialisers were not selecting the correct flags so the import was failing.
Added a test that uses the base provider so that a export/import happens for serialization.
