Example 1. A group folder used in Example 2.

Example 2. A default shared folder and a group folder. Observe how the color differs between the two

Group folder icon disobeys Nextcloud color support as seen in Example 1.

version: 1.0.2

Steps to reproduce:

1. Set the main color to something (Distinctly) different from the default and wait for it to apply. (Black in example images).
2. Create a group folder.
3. Go back to Files view.
4. Observe how Group folder icon is still in the default blue.

Expected result:
Group folder icon should change based on the theme color. (Black in example 2.)

Actual result:
Group folder does not apply the theme color.
