Description

This change is updating the column name for getting vulnerability aliases from vulndb

Current behaviour
The current query for getting vulnerability aliases for vulndb as source in the getVulnerabilityAliases method is query = pm.newQuery(VulnerabilityAlias.class, "vulnDb== :vulnDb"); which has column name invalid.

Expected behaviour
The correct id column for vulndb id is vulnDbId and thus the query should be query = pm.newQuery(VulnerabilityAlias.class, "vulnDbId == :vulnDb"); so that there is no error.

Thanks @mehab! 🙌

If my understanding is correct, this bug is currently breaking the VulnDB integration.
