Fix char conversions in QML

This is a partial revert of 90b06e2773842, as it had unwanted side
effects. The original intention was to make assignment from char to
string possible, or more specifically, we wanted a solution where a
QChar could be assigned to a QString, as a character and not a string
representation of its value. While this behavior is desirable for
QChar, we most likely want the opposite for the regular character types.
