[2.1.17] Checking and unchecking the "Parameter" checkbox in blueprints forgets quality

[elfakyn]

When you create a blueprint that contains recipes with higher quality ingredients, and then you parameterize and un-parameterize those ingredients, the original quality information is lost.

Steps to reproduce:

1. Blueprint something that takes quality ingredients/has a quality recipe.

The result is that the original quality value has been forgotten.

What I would expect: After checking and unchecking the Parameter checkbox, it's as if I never toggled it in the first place - whatever I had initially remains. I would also expect that when checking the Parameter checkbox, the resulting parameter would have automatically been set with the same quality (i.e. an Epic "0" parameter).

I've found these two threads that this may be a duplicate of: viewtopic.php?p=683992#p683992 and viewtopic.php?p=696691#p696691 but this seems different so I'm reporting it.
