Seems like we could expand this test case to try to simulate this bug. I think @jrmartin had a theory about the case in which this problem could happen that he could try to implement here.

Should be closed in https://github.com/openworm/org.geppetto.persistence/tree/experiments_table_refactoring -- new tests in https://github.com/openworm/org.geppetto.persistence/blob/experiments_table_refactoring/src/test/java/org/geppetto/persistence/db/DBManagerTest.java appear to cover this.
