Fixes bug in GinJavaBridgeDispatcherHost

Fixes bug in GinJavaBridgeDispatcherHost

My try job kept failing on android and I finally tracked it down to
this code. GinJavaBridgeDispatcherHost::RemoveNamedObject may be
invoked with a value that comes from named_objects_ (see
AddNamedObject). RemoveNamedObject removes from named_object_ and then
uses the passed in value. If this happens |name| is no longer valid
and shouldn't be used.

I'm TBRing so this'll land. This feels fine to me as you wrote the code, it's a
trivial change, and I'm in owner in a parent dir.

My bad. I really meant LGTM when replying, but forgot to actually type it.
Sorry, and thanks again for the fix!
