conversation_view.vala: update_highlight on touch event

Mobile devices such as the PinePhone do not receive leave/enter
events, so actions such as editing a previous message are not possible
unless a keyboard shortcut is used, which not be as convenient or even
possible under some DEs.

This commit should not affect desktop platforms with mouse or
touchpad.
