Bug: Handling of symbols when used as deps incorrectly to create error message results in an unrelated TypeError: Cannot convert a Symbol value to a string

React version: 16.3.1 ## Steps To Reproduce 1. Click the button in this Code Sandbox https://codesandbox.io/s/blissful-sun-e0lle?file=/src/App.js ## The current behavior The wrong error is generated ## The expected behavior An error should still be generated but the error message should be correct. The problem is that if you do `[Symbol('...')].join(',')` JavaScript will freak out which is what happens if you put symbols incorrectly in the deps to hooks.
