Empty temporary directories created for each match in result, but never deleted

[thomaskrause]

What is the used ANNIS version?
3.5.0-preview8

What browser and operating system did you use?
Ubuntu 14.04

What steps will reproduce the problem?

1. Start a query, show or export the results

What is the expected result?

Clean temporary directory after results are closed again

What happens instead?

For each match there is an empty temporary file in the /tmp folder with the patthern /tmp/<unix-timestamp>.+

Please provide any additional information below. Also please add a screenshot if possible.

These temporary directory where created to have a document for an SDocument that is created when the match is mapped. There might been a bug in Salt that made it necessary to have a valid directory for this, but with current Salt versions leaving this value null is ok. Since it is difficult to track when the directory could be deleted, not setting it at all seems to be the best solution,
