more cache hits for getMaxTickWidth

[panthony]

This PR:

• removes withoutRecompute and always return cached version if exists
• reuse addToCache and getFromCache instead of custom property
• add call to resetCache when redraw is called.

This way we have more cache hits and the cache is dropped each time we want to redraw the chart (thinking of resize etc.) which should be, hopefully, sufficient.
