no-unused-prop-types: Potential regression introduced in 7.5.0 #1542
Description
Hi there.
Noticed that my lint step failed after tagging my library with no code changes:
https://travis-ci.org/LINKIWI/react-elemental/builds/304035438
https://travis-ci.org/LINKIWI/react-elemental/builds/304036629
Interestingly, the failing build pulled in 7.5.0 of eslint-plugin-react which was published a couple minutes before the build kicked off.
I haven't had time to do thorough investigation yet, but the 7.5.0 release seems to have introduced a regression in no-unused-prop-types:
Cannot read property 'properties' of undefined
TypeError: Cannot read property 'properties' of undefined
