Edit-Config tag failing

It seems that the `edit-config` tag fails to find the plist property `LSApplicationQueriesSchemes`. It throws the error _**"Error: doc.find is not a function [ERROR] An error occurred while running cordova prepare ios (exit code 1)."**_ when I run `$cordova prepare ios.` If manually edit my plist file and add the below code, my apps functions fine and I can launch the external apps.

## Config.xml
```

Start by reproducing the failure with the shown Config.xml and `cordova prepare ios`, focusing on the `edit-config` handling for `*-Info.plist` and `LSApplicationQueriesSchemes`. Done means the command completes without the `doc.find is not a function` error and the requested plist entries are applied.
