Fix bug in legacy schematic I/O plugin. 

Move adding LIB_PART to library until the part is fully parse.  The problem
was unique_ptr was cleaning up the part when an exception was thrown during
parsing causing a double free when the cache was deleted.

Add missing try/catch block when loading the cache library during an append
schematic operation.

Fixes lp:1663869
