Twitter updated their framework's name

[SirArkimedes]

• Objective C or Swift: Swift
• iOS version: 11.2
• Firebase SDK version: 4.8.0
• FirebaseUI version: 4.5.0
• CocoaPods Version: 1.3.1

Problem:

Twitter updated their framework name and FirebaseTwitterAuthUI uses the old name. This is a breaking change if TwitterKit & TwitterCore are updated and FirebaseUI is included in the project.

Steps to reproduce:

1. Clone this repo
2. pod install
3. Start a build of FirebaseTwitterAuthUI
4. Notice that TwitterKit.h is not found

Observed Results:

• Get a "TwitterKit/TwitterKit.h is not found" error.

Expected Results:

• FirebaseUI works with latest TwitterKit & TwitterCore.

I am willing to submit a PR to fix this issue:
#381

Nice catch. PRs are always welcome, if not I'll fix this in the new year since I'm on vacation soon.

For the time being, people who run into this issue can work around it by pinning the Twitter SDK to an older version.

This is fixed in the latest release.
