Travis tests are flaky

[deepu105]

Our travis builds are acting very flaky recently. We had to restart several jobs to get it pass.
Here is an example https://travis-ci.org/jhipster/generator-jhipster/jobs/192443191

Most of the times the failure is from Protractor and sometimes JWT or cassandra builds

Its really annoying and time wasting

Yes I notice that since we migrate from firefox to chrome. I try to analyse the reason but it's really hard because it's totally random.

So sorry @deepu105 but be sure as soon as it's possible, I ll try to reduce these random failures.

One of the reasons I switched to Firefox last year was because I saw issues with Chrome and logging out. Sometimes it worked, sometimes it didn't. It always worked with Firefox. However, it looks like there's still issues with Protractor and the latest Firefox. angular/protractor#3750

Most failures I had recently were legitimate, I didn't notice that.
I'll be more careful about it.

@pascalgrimaud since its mostly protractor can we try to catch if there is a failure and retry once again just the protractor step?
I know its not a solution but I'll rather have that then to go and restart builds manually

@deepu105 : it's sound ok for me. I will give a try
