Fix/templatestorage
Motivation
Downloading files from the Wrapper via the TemplateStorage has a synchronization bug More information in #1294
Modification
Most important change: Moved the RemoteTemplateStorage from the driver to the wrapper Unless there is some future API planned, this should be fine because the RemoteTemplateStorage is only used in the wrapper and as far as I understand it remote storages from node to node are not allowed.
Otherwise in RemoteTemplateStorage I had to add a reference to the TemplateStorageCallbackListener which modifies the creation all the way up to the Wrapper class
Most of the logic itself is in the TemplateStorageCallbackListener, we could refactor the logic to somewhere else but my opinion is: what's the point?
I also modified temporary file creation. This could be left out, but it really is smarter not give the possibility to overwrite temporary files someone else created
Result
the TemplateStorage API works again
Other context
Fixes #1294
