Capture instance uuid and product id's when user selects instance

Purpose: to avoid duplicating instance and holding information.

Scenarios:
Scenario 1

• Given user adds title to order form by selecting instance from inventory
• When selecting instance
• Then system should capture uuid of instance
• AND capture valid Product ID's to populate order form product id and type fields
• NOTE: there's a bug related to some Product ID types - see MODORDERS-261

Scenario 2

• Given the user has added title to order form by selecting instance from inventory
• AND system has captured uuid
• When user edits or removes any of the imported information
• Then scrub uuid
• NOTE: there's a bug related to saving the PO once the data has been edited and UUID scrubbed - see MODORDERS-262

Scenario 3

• Given the user has added title to order form by selecting instance from inventory
• AND system has captured uuid
• When user adds additional info (Contributors product id's etc)
• NOTE: UUID is not scrubbed when Contributor or Product ID is added. UUID is scrubbed when Publisher or Pub Year are added. dennisbridges If UUID shuold not be scrubbed in those cases, please add a small follow-up story.
• Do NOT scrub uuid

Acceptance criteria:

• all scenarios work as expected;
• test coverage >= 80% on new code.
