As a Developer I want that the asic container unit tests are fixed and enabled so that I can get feedback on them

[raits]

The asic container verifier unit tests are currently disabled. See https://github.com/nordic-institute/X-Road/blob/develop/src/asicverifier/src/test/java/ee/ria/xroad/asicverifier/AsicContainerVerifierTest.java#L57. In this task the unit tests will be enabled and fixed so that feedback on the asic container verifier is always provided when the X-Road build is run.

The JIRA ticket this issue was created from can be found here: https://nordic-institute.atlassian.net/browse/XRDDEV-188

Acceptance criteria

• [ ] The asic container verifier unit tests are enabled and executed when X-Road is built
• [ ] The asic container verifier tests are brought up-to-date and working with the current version
