EDS TextField adds an aria-describedby for a non-existing item if there is no helper text

[wenche]

Describe the bug

We are using the TextField component with the multiline feature. Axe devtools reports an error regarding the aria-describedby. It seems like it is because the TextField component always adds an aria-describedby even if there is no helper text added.

Steps to reproduce the bug

1. Create a TextField (multiline, no helperText)
2. Use the inspector tool and notice that aria-describedby="eds-helpertext-number" is added even if this element doesn't exist

Expected behavior

Should not add aria-describedby for non-existing elements

Doh! Thanks for the notice.

We are currently re-writing all our "input" components, so we'll fix this in the "new" component.

Will be fixed by #2336

There was a bug in the inputwrapper so id was always set to null on the helpertext. I'll fix it
