Reproduction steps
Type 'lettu' in the emoji search, then backspace and retype the u a few times.
Expected behaviour
Show the matching emoji exactly once each.
Actual behaviour
gets duplicated each time the u is retyped. Probably because both 
are named :e_mail:, so it doesn't know which one to remove. Similar happens to 
, if you type woman_with_h.Build information
