Description
Issue Description
Parallel requests to install und deinstall an application package leads to a crash due to null pointer calls.

Reproduce
The issue could be reproduces by using the "appman-controller" and place in parallal calls to
appman-controller remove-package -f <PACKAGE_ID> appman-controller install-package <PACKAGE_PATH>
Be aware that calls should be parallel, so for instance I used two different bash scripts in infinite loop to reproduce the issue.
