App config.xml does not update AndroidManifest.xml file's versionCode, versionName or anything

# Bug Report
App config.xml does not update AndroidManifest.xml file's versionCode, versionName or anything
## Problem
I have changed app version, add some meta-data at android scope in config.xml file but after build it does not update android 'AndroidManifest.xml' file. I still see the previous value and meta-data in 'AndroidManifest.xml'.
### What is expected to happen?
changing on app config.xml file [app version, meta-data], should be changed in android 'AndroidManifest.xml' file after build.

### What does actually happen?
After changing app config.xml file widget version, meta-data, when the build finished nothing updated in AndroidManifest.xml file. And it shows no error, warning in build console/terminal. Build was success.

## Information

Changes on config.xml file data [app widget version], it changes automatically app version for the first couple of builds but after 6-7th time cordova build it does not automatically update. 'AndroidManifest.xml' so my android build version not updating and meta-data not added.
