Remove or fix Flaky tests

[andre15silva]

There are some flaky tests currently.

I have identified two so far:

• repairnator/src/repairnator-pipeline/src/test/java/fr/inria/spirals/repairnator/pipeline/TestPipeline.java

  Line 55 in 103e641

  public void testPipelineOnlyGitRepository() throws Exception {

  Failed and Passed
  Reason: org.eclipse.jgit.api.errors.TransportException: Connection timed out (Connection timed out)

• repairnator/src/repairnator-pipeline/src/test/java/fr/inria/spirals/repairnator/pipelineb/TestPipelinebGithubMode.java

  Line 67 in 103e641

  public void testPipelineGitRepositoryAndCommitIdWithFailure() throws Exception {

  Failed and Passed, Failed and Passed
  Can't determine reason because there's no access to test report

Can we close this one?

This still happens from time to time, so I think it's better to keep it open.

Another flaky test identified:

• repairnator/src/repairnator-pipeline/src/test/java/fr/inria/spirals/repairnator/process/step/TestGatherTestInformation.java

  Line 109 in 103e641

  public void testGatherTestInformationOnlyOneErroring() throws IOException {

  
  Failed and Passed
  Reason: sometimes the error message of the test project returns two lines without \n separating them
