Debugging QML doesn't work with enterprise-charts demo

Reproduced with apalis-imx6.

Steps to reproduce:

1. Install 5.15.0-RC2 b2qt binaries for apalis-imx6
2. Do the usual stuff (flash b2qt device with the wizard and add the device to creator)
3. Launch creator
4. Select enterprise-charts demo
5. Set a breakpoint
6. Start debugger

Expected result:

Debugger stops in the breakpoint and no errors are shown.

Actual result:

Debugger stops in the breakpoint (on Linux) but gives: "
QML Debugger: Ignoring "-qmljsdebugger=port:10003,block,services:DebugMessages,QmlDebugger,V8Debugger,QmlInspector". Debugging has not been enabled."
On Windows the debugger crashes.
