Input language on top bar when using "Terminal" variant of squeekboard is not always latin/english.
### Describe your issue
I use the Greek keyboard in some cases. Changing from "Greek" to "Terminal" typing will not change the "gr" icon on the top bar, although "Terminal" uses by default Latin characters.
#### Expected Behavior
When selecting "Terminal", either display "en" or nothing at all on the top bar.
