[IndexedDB] Should removeIndex/ObjectStore be renamed to match s/remove/delete/ elsewhere?

Jonas just checked in a change to replace .remove() with .delete() (amongst
other changes we agreed upon a while ago).  In light of that, does it make
sense for removeIndex and removeObjectStore to be renamed to deleteIndex and
deleteObjectStore to match the new naming?  I don't care a whole lot, but it
seems like that'd make things more consistent.

Thanks,
Jeremy
