Circe is broken in community build

[ashawley]

There isn't a lot in master, since 1.14.0 was released, but the community build uncovered a test suite error in circe that could be ScalaCheck related:

[ashawley]

Seems it could be #401.

[ashawley]

Should probably add a test to the test suite to verify Arbitrary.arbOption can handle recursive generators. This wasn't a scenario that had been considered, but maybe there's a way to accommodate it by changing the frequence of Some v. None.

[ashawley]

Should be fixed in circe/circe#1204
