Fix QML compatibility for Text.contentWidth/Height changed handlers

The properties used to have a single notifier that name is different from
the properties names. QML Engine always connects a handler to signal, if it
exists and only if there is no such signal then it lookup for a property
notifier. In commit e92f76cf9ea91e87ec2e3e68234899fd9c12142f we introduced
new signals that match the names of the two property changes handlers, but
the signals are not available on older import.

Remove revision number from the notifiers of Text.contentWidth/contentHeight
to fix backward compatibility until a better solution (such as extra engine
logic like "if a signal that matches the handler is not available then check
if there is a way to connect to a property notifier that matches the handler"
