Change notransition technique

[atomiks]

Fixes atomiks/tippyjs-react#67

Changes the "notransition" technique which fixes undesirable transitions when the tippy changes placements on updates.

Before: add a transition: none CSS class on the tippy once onShown() completes

After: use some instance flags to check if the previous placement is the same and if the previous update happened while the tippy was visible. If so, disable transitions for a single frame before painting. This is a better way to do it anyway and it fixes the problem linked

(going to be deleting the comments describing the variables after this as they're quite redundant, that's why I didn't add any here)

@atomiks Thanks for the quick fix! I assume this will be included in tippy.js@4.2.1, but since tippy.js-react depends on tippy.js^4.0.4 right now, could you update it to tippy.js^4.2.0?

@Lazyuki that semver range means when you update @tippy.js/react you'll get the latest tippy.js version anyway.

Run

npm i @tippy.js/react@latest

in your project. I'm going to release this patch today
