Error: Symbol not found: _OBJC_CLASS_$_GULKeychainStorage

### Step 0: Are you in the right place?

Yes i'm in the right place

### [REQUIRED] Step 1: Describe your environment

  * Xcode version: 11.4.1
  * Firebase SDK version: 6.23.0
  * Firebase Component: GoogleUtilities
  * Component version: 6.6
  * Installation method: CocoaPods

### [REQUIRED] Step 2: Describe the problem

#### Steps to reproduce:

After updating firebase to the latest version (6.23.0), I get this error immediately after starting the application. The error appears on the simulator and on the real device (iPhone 11 Pro, iOS 13.4.5), but the mac catalyst application successfully starts. I suspect that the error is caused by this PR: #5329
