Fix bug that caused a single run event to create multiple jobs

[collado-mike]

Signed-off-by: Michael Collado collado.mike@gmail.com

Problem

As described in #2158 a single run may send multiple run events, where the start event contains a parent run and subsequent events do not. In that case, the subsequent jobs will create a new job without a parent, causing duplicate jobs with the same name.
Closes: #2158

Solution

During OpenLineage event handling, check to see if a run with the given id already exists. If it does, do not create a new job (or parent), but simply use the job that is already associated with the run.

Note: All database schema changes require discussion. Please link the issue for context.
