Spot another clang-tidy linter failure from: #56631

In release mode, if we remove NSAssert, then weakFlutterEngine is not used at all. This should have been an XCTAssert rather than NSAssert in the first place.

❌ Failures for clang-tidy on /Volumes/Work/s/w/ir/cache/builder/src/flutter/shell/platform/darwin/ios/framework/Source/FlutterTextInputPluginTest.mm:
/Volumes/Work/s/w/ir/cache/builder/src/flutter/shell/platform/darwin/ios/framework/Source/FlutterTextInputPluginTest.mm:239:5: error: Value stored to 'weakFlutterEngine' is never read [clang-analyzer-deadcode.DeadStores,-warnings-as-errors]
  239 |     weakFlutterEngine = flutterEngine;
