fix(plugins/core): Handle missing tests in get_assignment calls

This commit fixes an issue where generic runs would fail to submit due
to not finding a test entity associated with a run when storing a
version. It adds exception handling to submit_product_version on every
plugin to fix that.

Fixes scylladb#524
