Use IDL argument default values in modules/indexeddb/
Replace bogus 'null' default values for DOMString arguments with the
actual default values from the spec, and remove the handling of null
strings in the C++ implementation.
Also replace [Default=Undefined] on some boolean arguments with the
default value 'false' from the spec, which has the same effect.
