edje_cc: Fix TEXT part validation for aliased parts

Not 100% sure of this fix but it "works". This is just compile-time
safety checking code after all, so it won't impact any existing
application.

This fixes commit d4444bf7a0e368097bec555. Tested with empc.

Thanks @zmike for the report and test case.
