the file being locked may have been changed sinc the client synced it
so the server side file may have a modified etag. In such cases we do
not want to lock the file and would rather sync the nex server changes
before being able to lock the file
that would ensure that on client side the file being locked is matching
teh state of teh file on server side and would prevent inadvertently
overriding server changes
