Fix using of custom AndroidManifest.xml

In case user had edited his AndroidManifest.xml, he may have removed the com.tns.ErrorReportActivity. In this case, NativeScript CLI thinks that the AndroidManifest.xml is not correct, creates a backup for it and extracts the default one from the template.
Remove the check for `com.tns.ErrorReportActivity`.
