Fix bug testing input validation

[MikeLautensack]

Testing input validation is currently not working.

Potential causes:

1. The test is written incorrectly
2. The rendering of the error text in the helperText prop may be causing unexpected behavior

Potential Fixes

• [ ] Adjust test for async behavior (low confidence)
• [ ] Try using a FormError component to render error text (moderate confidence)

Fix:

1. await user events
2. wrap events that update state in act func
