first approach in #46: test works well
TestStormWrapper moved to globaleaks.transactions.GLBackendTransactor
temporary commit that shows some refactor ideas
implemented the same as the previous commit also fot create_new_receiver

new refactor working up to:
./admincycle.sh
1) Disabling all the scheduled jobs ... done.
http: warning: HTTP 500 Internal Server Error
2) Creating Context 1 ... done.
http: warning: HTTP 500 Internal Server Error
3) Creating Receiver 1 ... done.
on context creation all dates can be aligned:

by doing this the check self.creation_date != self.update_date can also be used.

this behaviour has to be corrected in quite all models.
Package globaleaks.tests; remove __init__.py from _oldtest.
Tests ordering, wtf.
reviweing config:
-removing unused imports.
-removing useless functions for manupulating paths and checking directory existence
-pep8
-removing useless exceptions
