[0.15.2] Blueprints clutter inventory

[DemoBytom]

Description: When you pick up blueprint from blueprint library, close the library and clear the cursor the blueprint ends up in the inventory, even creating duplicates.

Steps to reproduce:

• Open blueprint inventory
  Pick up blueprint
  Hit E to close the blueprint inventory
  Hit Q to clear cursor

Expected behavior: When you don't, on purpose, put a blueprint from the library onto a quick bar and/or bag slot the blueprint should disappear instead of being send to the bag.

Actual behavior: Blueprint ends up in the bag slot, cluttering it, impossible (to my knowledge) to be removed

Example:

You can drop them on the ground or put them into a box (which can be destroyed). But it is confusing.
