[WIP] changing sleep time + order of travis steps

[benkeen]

There's a problem with the travis config in that sometimes the mocha tests fail, e.g.
https://travis-ci.org/apache/couchdb-fauxton/builds/62419139
https://travis-ci.org/apache/couchdb-fauxton/builds/62403433

I can reproduce this locally when Fauxton isn't running when mocha is started. This PR is trying out some different configurations like increasing the sleep time and changing the order to ensure tests run after the server has been started.

./node_modules/grunt-cli/bin/grunt dev & means the process is forked into the background and running there.

running the tests while running the other process in the background builds a special test release which will overwrite the release created by grunt dev

what are you trying to archive, the commit message does not mention the problem...?

Hey @robertkowalski - this is just a test PR. I'll add [WIP].

Yes, I know the & runs it in the background - I just added a comment above explaining what I'm doing.

Results:

1. First attempt yields build error -npm ERR! EEXIST, symlink '../esprima/bin/esparse.js'' possibly caused by Spurious issue running tests on travis. jscs-dev/node-jscs#883. Re-running.
2. Second runs + passes all mocha tests. So issue in 1 doesn't always occur. All NW tests are failing.
3. Third time, there was a new error right off the bat: W: Failed to fetch http://us.archive.ubuntu.com/ubuntu/dists/precise-updates/universe/source/Sources Hash Sum mismatch
4. Fourth: success! builds, runs fauxton, runs mocha tests, runs NW tests (which may or may not all succeed - the failing NW tests will be addressed separately)
   5: success.
