fix: Better consideration of the negated matcher in waitUntil

[dprevost-LMI]

Fixes #1982.
Now:

• We considered isNot when wait = 0
• We run the condition function until the timeout, so it can become true before checking for the negation of it
• Fixes multiple UTs whose titles were even correctly named but had the wrong assertions

Bonus: Fix toHaveElementProperty typing in the d.ts file

[dprevost-LMI]

We run the condition function until the timeout, so it can become true before checking for the negation of it

Might need a second opinion here, since now when using expect().not, the test will be slower since we need to "always" timeout
