Catch IllegalArgumentException when resolving target definition

When the target editor is opened, PDE tries to delete the old target
handle as part of "Bug 545681 - UI Freeze of >800s in TargetEditor when
opening editor".

If the profile is not locked (due to whatever reasons), an
IllegalArgumentException is thrown, blocking the resolution of this
file.
