Subject: [PATCH] X509 fixes (#111)

* Return proper content type for the x509 certificate

* Remove parenthesis

* Remove extra-variables during the import

* Comment fix

* Remove double returns

* Change log level from trace to debug

* Remove 'pass' and add logging instead

* Remove unnecessary wrapping

Remove wrapping

* PEP 8: line too long

PEP8: line too long

* PEP8: Redefine RSAError variable in except clause

* Do not return None if name was not found

* Do not return None if no matched minions found

* Fix unit tests

Fix for log checking in x509 test

We are logging in debug and not in trace mode here.
