Fixed issue with float vectors assertion during tests

`sequence.feature` - Added `[:]` to make errors more readable values in errors (for example, (0.20000000298023224, 0.20000000298023224, 0.20000000298023224, 1.0) instead of `<bpy_float[4], Object.color>`

`test_feature.py` - fixed `FAILED test/bim/test_feature.py::test_animate_the_consumption_of_a_wall - AssertionError: Value is <bpy_float[4], Object.color>`
Test was failing because of float garbage in object.color (the comparison was (0.20000000298023224, 0.20000000298023224, 0.20000000298023224, 1.0) <> [0.2, 0.2, 0.2, 1] )

After that fix all tests now are passed 🥲
