Support testlink-java-api 1.9.20-1

[Martin-vH]

Upgraded TestLink instance to 1.9.20, afterwards the Jenkins project using the TestLink plug-in 3.16 failed with the known error:

12:30:22 FATAL: Error verifying developer key: Failed to parse server's response: Expected methodResponse element, got br
12:30:22 br.eti.kinoshita.testlinkjavaapi.util.TestLinkAPIException: Error verifying developer key: Failed to parse server's response: Expected methodResponse element, got br

As there is no plug-in version using testlink-java-api 1.9.20-1, this is the PR for it. Needed to adjust reportTCResult to fix the following error:

Testing done

The Jenkins project uses the basic build steps:

1. Invoke TestLink (here the initial error occurred due to the version incompatibility)
2. Test Execution
3. Iterative Test Build Steps
4. After iterating all test cases Build Steps
5. Result Seeking Strategy: TAP file name (here, the reportTCResult error occurred)
