Embedded Relationships Bug

[wrbrant]

Embedded relationships won't show up sometimes if some of the objects with ids in an observed-data's objects_refs list are not loaded into STIG. For example:
An observed-data object has 10 process ids and 10 file ids contained in its object_refs. These are all stored in the database. If the query was

match (o:`observed-data`)
match (p:process)
return o, p

1 observed-data object and 10 process objects would be displayed. However, if the user selects View Embedded Relationships, some of the expected relationships between the observed-data object and the process objects will not display. It appears that when STIG encounters an id that is not on the screen, it stops making embedded relationships. This needs to be fixed, since there are appropriate times for the situation where every object in observed-data objects_refs would be on the screen.
