Fixes corruption of e4xmi files when class is renamed

The corruption happens in a setup with a top level Maven project and plug-in projects in sub directories (eg bundles).
If the name of a Java handler class is renamed in the Java file
-the e4xmi file is found twice with
-- full workspace path
-- plug-in project path
This leads to 2 changes in one e4xmi file with the same text, offset and length.
If the old and new names are of different length the corruption occurs.
This fix skips the file if any of the paths (workspace or project) are already included for renaming.
