#266 #302 #293 Prevent crash when using types with spreads

[kusmierz]

This is solution 1 (so I won't update babel-eslint nor add proper tests) from @lydell #266 (comment). It also fixes crash for sortKeys rule. Not the best solution though, but should work in the meantime.

#266 #302 #293

@gajus any plans to update babel-eslint?

Babel 7 RC is going to come out in a couple of days.

I will create/ accept a PR that updates to Babel then.

It would be reasonable to start working on one as the only breaking change outstanding is babel/babel#7358.

Babel 7 has been coming out in a couple of days for half a year. #266 (comment)

(All respect to the awesome Babel maintainers, I totally understand it takes time to get it right.)

The point is that now there are no more planned breaking changes (other than the PR I have linked). At the time it was well known that breaking changes are to be expected.

@gajus noDupeKeys started working, but sortKeys still broken. Any chances to fix it before Babel 7? :)

[kusmierz]

@gajus babel/babel#7358 seems to be merged now. How could I help with that issue now?

[gajus]

The next step would be babel-eslint to version 8.2.3. However, it breaks bunch of tests currently. I have not had time to investigate.

#293 is closed/fixed, so I think this PR can be closed as well now?
