Can't persist some options.

[CyrusNajmabadi]

When i try to persist some options (like SymbolSearchOptions.SuggestForTypesInNuGetPackages) i get the following exception:

System.InvalidCastException: Unable to cast object of type 'System.Boolean' to type 'System.Collections.Generic.List`1[System.Collections.Generic.KeyValuePair`2[System.String,System.Object]]'.

I believe that @jmarolf found that this was a red-herring, and the actual issue was with the settings host process missing a binding redirect, which has now been fixed.
