Reproduction steps:
1) Create a new project
2) Switch to Android platform in Build Settings
3) Make sure that package name is set to default (com.Company.ProductName)
4) Build the project
5) Notice that "Bundle Identifier has not been set up correctly" error message is being thrown

Expected results:
This error message tells what to change: "Please set the Bundle Identifier in the Player Settings."
but as "Bundle Identifier" field has been renamed to "Package Name" in Player Settings, the error message should be renamed too
