Testing of directly adding/removing items

[jaybuidl]

• Test it
• Check that the subgraph and frontend can pick the items added directly
• Modify the function to take an array as parameter

From @greenlucid

addItemDirectly and removeItemDirectly are not emitting RequestSubmitted

fixing it could just be editing subgraph to create default Request Entity on ItemStatusChange with no Request associated

frontend crashes because it expects request to exist request doesn't exist because subgraph does not handle properly subgraph could handle it properly
