Fix SVG style for eye icon on warning toggle
Fix SVG style for eye icon on warning toggle

Summary:
The SVG images used for icons aren't consistent--a part of
the eye would change location on the screen when toggling
between active and inactive. This copies the path used in
one of the icons so the two are the same.

Test Plan:
* `make test`
* Verify in browser
