Augmentation grade cost not shown correctly when adding plugins

[aga9]

Describe the bug
The cost modifier of cyberware/bioware appears to be only applied when the grade is changed, and when the item is actually added. This causes the problem of cost not being displayed correctly when adding a plugin to a non-alphaware cyberware.

To Reproduce
Steps to reproduce the behavior:

1. Go to cyberware, add any non-alpha cyberware.
2. Add a plugin to that cyberware.
3. Note that the grade is already set to the grade of the parent ware.
4. Error: note that the cost displayed is still alphaware cost instead of the appropriate grade.

Expected behavior
The cost displayed should be appropriate to the grade.
