[charts] Ignore empty tick labels in label overlap computation

[alexfauquette]

The issue is that previousTextLimit was updated even is their is no text to display. So frequently for log scale axis, the 90k tick which is very close to the 100k tick update the previousTextLimit and prevent the 100k tick to render.
