Problem types `object.toString()'s` end up in URIs; don't know what to do about this.

<|cpp+parameter:///Phonebook/searchByPhoneNumber(org.eclipse.cdt.internal.core.dom.parser.ProblemType@31e76a8d)/phoneNumber|,|project://clair/src/test/phonebook.cpp|(1100,11)>,

Duplicate of #25 (which has a misleading title). The toString originates from lang.cpp.BindingsResolver in the printType(IType) function.

Note that the underlying issue is that the type of the first argument of searchByPhoneNumber cannot be resolved by CDT.
