Non-null assertion and overload resolution ambiguity

[farruhha]

After cloning the master branch, the project does not compile. I get the following two compile errors.

1. e: /Volumes/Zume/external/plaid/core/src/main/java/io/plaidapp/core/dribbble/data/search/DribbbleSearchConverter.kt: (111, 34): Only safe (?.) or non-null asserted (!!.) calls are allowed on a nullable receiver of type String?
2. e: /Volumes/Zume/external/plaid/core/src/main/java/io/plaidapp/core/util/SpringUtils.kt: (98, 31): Overload resolution ambiguity: public open fun remove(@Nullable element: DynamicAnimation.OnAnimationEndListener): Boolean defined in java.util.ArrayList public open fun remove(@Nullable element: DynamicAnimation.OnAnimationEndListener!): Boolean defined in java.util.ArrayList

Thanks.
