When initializing react native module using a url pointing to local jsbundle and hot reload is enabled, bridge, is trying to initialize the feature but crashes because there is no host in a local file url.
1. Create a new project.
```sh
$ react-native init testPlanApp && cd testPlanApp
```
2. Create jsbundle.
```sh
$ react-native bundle --platform ios --dev false --entry-file index.js --bundle-output ios/main.jsbundle
```
3. Run the app and enable hot reload.
4. Enable airplane mode.
5. Close application and re-run.
6. See app crashes.

Summary:
Remove fallback logic.
It is hard to test whether a bundle is good or bad on device, since it does the fallback, remove the fallback logic now.

Summary:
This fixes the `testModulesAreDeallocated` test. It was sometimes failing because the bridge's module was still alive. I debugged with the Xcode memory graph and found that the bridge was actually kept alive by a pointer from the NSThread.
By killing the runloop on the thread, the thread will eventually die and thus free the bridge.
One thing I didn't investigate was whether the thread was alive because of it receiving actual messages or just because the run loop was spinning.

Summary:
Output the reason for the error when failing to load source code. This was a big help when trying to diagnose https://github.com/facebook/react-native/issues/13299.
~~Unfortunately there still seems to be no way to get the offending line number (because `loadError.userInfo[RCTJSStackTraceKey]` is empty), but this is good enough.~~
Before:
```
[warn][tid:com.facebook.react.JavaScript][RCTBatchedBridge.m:510] Failed to execute source code. Unhandled JS Exception: SyntaxError
```
After:
```
