Title: fix entity group transactions with delete commands: don't send a content-type header for thse

Entity group transactions containing delete operations fail, and it appears to be because there's a content-type header (despite there being no content).

Also note that the original code referred to properties that don't seem to exist (ServiceClient.HTTP_VERB_*), so I just put the string constants in there instead ('GET' and 'DELETE').

On a side-note, it's probably wrong to include the content-length on a delete, but that didn't seem to cause an error, so I didn't touch that. This seemed to me to be close to the minimal change necessary to fix the bug.
