Alter get_text_range call based on VTE version

In vte 0.72 there was a regression that caused
Vte.Terminal.get_text_range() to fail to return the text requested
However, in the same version, there was a new call introduced that
does retrieve the text, so if I detect a vte minor version above
72, I call that instead.
