Tilesheets of linked Objects do not get included into the main file

Thank you for contributing to Armory!

**Description**
When linking an object which has a tilesheet attached to it. The tilesheet as well its action do not come over.
An error gets thrown and you get a black screen. When you create the tilesheet new as well its action with the same name as in the linked file in the linked material the error doesn´t appear but the tilesheet is still not playing.

**To Reproduce**
Link "Tux" from the tilesheet example into an new file.

**Expected behavior**
Tilesheet and its action shall come over to the new file.

**System**
Blender: 2.93
Armory: 2208
OS:Win11
Graphics card:RTX2080Super

**Test File**
*(drag & drop the zipped .blend file here)*

Reproduce the issue by linking “Tux” from the tilesheet example into a new Blender file. Check why the linked tilesheet and its action are not included, reproduce the black screen or non-playing tilesheet, and confirm that linked assets work without recreating them manually.
