[Taxonomy Plugin] Names for other languages should default to the English 'Name'

1. Create a taxonomy with en, es and de languages
2. Open taxonomy in CMS, and create a new entry in English with Key : test-es  &  Name : Test Es
3. Do not save and now select Spanish and give 'Prueba Es' as the 'Name'
4. It doesn't matter whether you save or do not save at this point. The outcome is the same. Now select German and notice that the 'Name' value generated is 'prueba-es', which is the last given name for Spanish in the previous step
5. At this point, even if you change the German name and save it, the default name for the next language you select will still be 'prueba-es'
6. Additionally, if you save after step 2, it displays 'test-es' , while the client expects the value to be 'Test Es' which is the given English name

The client expects the Name value to default to the English Name in all cases.
