axe-core/react should check whether axe-core is running before starting another run

[WilcoFiers]

Axe-core/react uses a debounce to try and prevent running axe too often. This is mostly reasonable, but if axe-core takes longer to complete than the debounce time it might end up starting another run before the prior one is finished. This results in an error, as reported here: https://github.com/dequelabs/axe-core/issues/3426#issuecomment-1650988499
