Filled icons in the sensor-observation card

**Describe the bug**
Some of the sensor icons in the sensor-observation card don't use the filled-icon version.

**To Reproduce**
Steps to reproduce the behavior:
1. Create an experiment
2. Click on "add sensor note"
3. Note that some sensor icons (f. ex. Accelerometer X, Y and Z) are not "filled"

**Expected behavior**
The icons in the sensor-observation card should all use the filled version. This is also the behaviour on iOS.

**Screenshots**

Reproduce the issue by creating an experiment, choosing “add sensor note,” and checking the sensor-observation card, especially the Accelerometer X, Y, and Z icons. Compare the card’s icons with the filled-icon behavior on iOS; done when all sensor icons use their filled versions.
