Fixes #1982.
Now:

• When not using .not, the result returned by waitUntil is still true for success and false for failure
• When using .not, the result returned by waitUntil is now always false for success and true for failure since Jest's expect framework inverts the boolean later on.
• No need to pass isNot anymore since we do not want to rely on it to fail fast, instead we wait for the condition to be true (or timeout) and test the same really has without isNot
• When we have an error, we simply rethrow it
• Added wdio matcher integration tests to ensure .not behaviour is conserved over time
• Added a test for the below example representing the initial bug targeted to be fixed

⚠️ Possible impact: if tests are running longer when using .not, this can be mitigated by passing a wait value in the option parameter

Bonus: Fix toHaveElementProperty typing in the d.ts file

Why do we need to wait?
Example: If we have a wait of 10 sec and the text becomes 'GOOD' at 5 sec
Then

expect($('myElement')).toHaveText('GOOD') 

will pass after waiting 5 sec

Also, with today's bug, if you do

expect(element).not.toHaveText('GOOD')

It will also pass because, on the first attempt, it is effectively false.

Having both above conditions pass for the same scenario does not make sense.
By waiting, we ensure we have the 'real' fetched value and negate that 'reality.'

Code representing the above example

  const el = await $('selector')
            vi.mocked(el.isDisplayed)
                .mockResolvedValueOnce(false)
                .mockResolvedValueOnce(false)
                .mockResolvedValueOnce(true)

            // Passes when element becomes displayed
            await expectLib(el).toBeDisplayed({ wait: 300, interval: 100 })

            vi.mocked(el.isDisplayed)
                .mockResolvedValueOnce(false)
                .mockResolvedValueOnce(false)
                .mockResolvedValueOnce(true)

            // Should not pass with the same scenario to be consistent
            await expect(() => expectLib(el).not.toBeDisplayed({ wait: 300, interval: 100 })).rejects.toThrow(`\
Expect $(\`selector\`) not to be displayed
Expected [not]: "not displayed"
Received      : "displayed"`)
        })
