Change get_name to get_pronunciation to clarify what's being used.

[betaorbust]

The current use of get_name preferentially returns the pronunciation instead of the name of a rule.
This change updates get_name to be get_pronunciation so the method name is more in line with the underlying logic.

Original:

def get_name(self):
    return self.name if self.pronunciation is None else self.pronunciation

Updated:

def get_pronunciation(self):
    return self.pronunciation if self.pronunciation is not None else self.name
