Fix crash when importing Eagle schematics with multiple module levels. 

Fix annotation when importing Eagle schematic modules.  Apparently Eagle
uses hard coded module name prefixing scheme to generate module symbol
references by prefixing module name separated by a colon.  Even though
this results in references that are incompatible with KiCad, they are
used so that the board and schematic can be synchronized by references
on import.
