Find/replace dialog: properly update search string eclipse-platform#2322

The find/replace dialog does currently not properly update its search
string. When changing the search string and pressing return to execute a
search, the previous search string is taken. The reason is an existing
workaround for event handling of Combos in GTK.

This change ensures that the search and replace input strings are
properly updated upon every text modification in the according widgets.

Fixes eclipse-platform#2322
