Fix unexpected ellipsize for long suggestion text.

Unexpected ellipsize issue happens after
Ic8445022634e9130f9462e02bfb08d4877396ba3. By setting match_parent to
ListView, the ListView does not expand to fit the suggestion item.

Thus, explicitly setting the ListView width instead of setting
match_parent or wrap_content.

I manually verified this CL does not revive Issue 27341560 or
unexpected ellipsize for shorter text.
