Swatched get duplicated when importing objects with the same color swatch if the original swatch is in a group.

To replicate the issue:
1. Import an object from Illustrator. A swatch is created.
OR Create a new swatch.
2. Make a group with said swatch or swatches.
3. Re-import same object from Illustrator. A new swatch will appear with the same name but ending in "2".

Eg. Although a "C=100 M=0 Y=0 K=0" swatch exists (in a swatch group) the new object (which is the same as before) will create a new swatch names "C=100 M=0 Y=0 K=0 2". If the same object gets imported again a third new swatch is created "C=100 M=0 Y=0 K=0 3"

When working with a brand manual's imported color swatches groups, this is very problematic.
