JSSymbolTableObject::deleteProperty() crashes deleting Symbols
https://bugs.webkit.org/show_bug.cgi?id=153816

Patch by Caitlin Potter <caitp@igalia.com> on 2016-02-02
Reviewed by Darin Adler.

Changes JSSymbolTableObject::deleteProperty() to check if its
symbolTable() contains the property's uid() rather than publicName().
This ensures that it will not crash in the case of Symbols.
