[REG 5.3 -> 5.4] Android: QFontComboBox Broken

It is nice to come back to Qt Android development,
and sorry for the new reporting.

It was working properly with Qt-5.3.1

To reproduce:

1. Use textedit example;
2. Build vs downloaded standalone 5.4.0 for linux-32 AS IS;
3. Run the example and observe that
the font combofox could be used only to write
there but not to select fonts - it's not selectable.

Attempted:
a) Setting style "fusion". The style re-styled, but the combobox
is not functioning;
b) setEditable (false). It makes it be like a label.
