Android: Fix duplicate class names when generating QML to Java code

Whe the QT_ANDROID_GENERATE_JAVA_QML_COMPONENTS flag is present the
AndroidDeployQt generates nested classes with the same name as target
and QML module names. When the target name is the same as the QML module
name, the code gets generated successfuly but will fail at compile-time
in the target user project.

With this fix, we detect such cases and fail early, providing a proper
output message
