ATLAS-5073: ensure propertyKey is created before using it (#401)
(cherry picked from commit 0c1c390dd94b6aed05b0386f80c43fb5de5d4566)
> Create Janus property keys before using them

> Atlas stores entity attributes as graph vertex/edge properties; a
> property-key (describing characteristics like datatype, cardinality) should
> be created before read/write of values in a vertex/edge property. If a
> property-key doesn't exist, JanusGraph will create one on first reference to
> the vertex/edge property. However, JanusGraph recommends explictly creating
> property-keys before using them - see the following at
> [https://docs.janusgraph.org/schema/:|https://docs.janusgraph.org/schema/]
> {noformat}
> It is strongly encouraged to explicitly define all schema elements and to
> disable automatic schema creation by setting schema.default=none in the
> JanusGraph graph configuration.{noformat}
>
> Atlas does create property-keys while loading typedefs; however, this is
> missed in few cases, resulting in such property-keys to be created on first
> reference. This should be fixed to avoid automatic creation.
