Subject: [PATCH] Fix XYToPosition() for the last position in first line in
 wxGTK

This is similar to e74fb5effe6542340af85d50970787c133a911af for wxMSW
and ensures that we don't consider the last position on the first line
invalid in wxGTK neither.

This fixes TextCtrlTestCase::XYToPositionSingleLine() unit test failure.
