Style fixed :) But looks like travis failed to install dependencies :( https://travis-ci.org/jerryscript-project/jerryscript/jobs/595415709 |

IMO return false; is enough here, the else block is unnecessary.

Would it make sense to return ECMA_VALUE_TRUE here?

I checked ECMA spec for the return value. It's expecting null. I'll update to be compliant with the spec. Would this be ok with your suggestion?

Here we also should test that the type of the return value is ok. By using to_boolean we force a conversion if the return value was not a boolean. We can simply use the jerry_get_boolean_value.
