Codeceptjs: grabValueFrom returns empty array on firefox and new codeceptjs version

[yogainalift]

Getting empty array for firefox when trying to grabValueFrom element

Additionally chrome returns array of 1 element even though there was only 1 result.

Console output with --verbose flag enabled (relevant part for firefox)

Emitted | step.passed (I wait 2)
Emitted | step.finish (I wait 2)
Emitted | step.start (I grab value from "#exampleFormControlSelect1")
I grab value from "#exampleFormControlSelect1"
Emitted | step.passed (I grab value from "#exampleFormControlSelect1")
Emitted | step.finish (I grab value from "#exampleFormControlSelect1")
[]
Emitted | test.passed ([object Object])
Emitted | test.finish ([object Object])

Reproduction test

Scenario('check Welcome page on site', async (I) => {
  I.amOnPage('https://getbootstrap.com/docs/4.0/components/forms/');
  I.waitForElement('#exampleFormControlSelect1');
  I.selectOption('#exampleFormControlSelect1', '5');
  I.wait(2);
  const value = await I.grabValueFrom('#exampleFormControlSelect1');
  console.log(value);
});

Found out this is due to deprecated method, I'll create a PR to fix this.

Hey PeterNgTr,

Thanks for trying to solve this issue unfortunately I can still reproduce this.

According to https://webdriver.io/docs/api/element/getValue.html the return value should be a string and not an array.

This is an issue when trying to run tests suits for multiple browsers.
