[Qt] 'modalSession has been exited prematurely'

[pafonta]

Specific to macOS. Related to Qt (not NeuroCurator).

It has been fixed in Qt 5.3.1. We are in 4.8.x. Details: https://bugreports.qt.io/browse/QTBUG-37699.

From https://codereview.qt-project.org/#/c/87814/, it seems that:

For modal dialogs not run through QDialog.exec(), the modal sessions were not cleaned up, causing the application's menus to be inaccessible.

Except this case (to be proven to be present in NeuroCurator), this message has to be ignored.

The message will disappear after #6 is fixed.

Fixed in v0.4.4 which is using Qt 5.11.
