android: re-apply custom language when webview appears (#5022)

* android: re-apply custom language when webview appears

There is a bug on Android related to including WebView. App language
changes to system language regardless of what was set before in
context's configuration. Re-set needed to be done twice: after creating
of WebView and after removing it from a view

* add link to bug
