TEIIDDES-1701: Small bug fixes for refactoring functions

* RelatedResourceFinder
 * Typo for ALL relationship.

* RefactorResourceUtils
 * Caters for real possibility that a group name appears in an SQL statement
   line more than once, eg. SELECT SourceModel.ID, SourceModel.name, rather
   than only finding the first.

* RenameResourceRefactoring
 * Only if SQL edits have been added to the TextFileChange should it be
   added as a change. Otherwise, an empty change object is added and makes
   no sense.
TEIIDDES-1654 adds logging for unexpected difference report errors

TEIIDDES-1694: Fix regression in edit server action

* When clicking on a Teiid Server in the ServerView, it should not be
  necessary to display the server selection dialog since the server has
  already been selected using the selection changed listener

* EditServerAction
 * The edit server action should have no knowledge of the default server
   and has no need try and get it itself. In all use-cases it should be
   provided with the server that it is editing.
 * The default constructor is invoked when using the action as a command
   handler. In this case, the server-to-edit is provided by the event's
   data object.
 * Since all use-cases have the server provided, the editDefault flag can
   be removed.

* ModelExplorerResourceNavigator
 * Provide the edit server command with an event containing the server-to-
   be-edited.
