[webview_flutter] Remove duplicate integration test (flutter#4666)

stuartmorgan-g · web-flow · commit ec80d3439adb · 2022-01-13T12:36:40.000-08:00
This test is for a change that was entirely in Android Java code when it was written, so is testing behavior that is internal to the Android implementation, and a copy of this test already runs webview_flutter_android. Given that it's testing internal Android behavior, only that copy is needed. For unknown reasons, this copy seems to hang test runs, while the webview_flutter_android copy does not. Since it's a duplicate that we want to remove anyway, this simply removes it to fix the tree without meaningful loss of coverage. Also fixes a race condition in an integration test, where a future could be completed more than once. Part of flutter/flutter#91004
