delegates: remove ComboBoxTemplate::fixTabBehavior

Browse source 
The comment states that Qt treats TAB as cancel when in the combobox.
However, testing shows that this use-case works without this hack.
Since it caused weird behavior (the data was set *after* the editor
was closed, leading to inconsistent state), remove it.

Note: this overrides the previous commit, which is therefore redundant
from a history point of view. However, I'll leave the previous commit
in so that if something turns out to break, we can figure out which
of the two changes it was.
