Run only HHVM on Trusty due to Travis inconsistancy

[photodude]

Some people claim that in some instances Travis can start slowly or run slowly. Reduce this issue by only running HHVM on trusty

[photodude]

@zdenekdrahos this PR should reduce the long runtimes you mentioned in #52 (comment)

I've seen some statements that Travis will randomly be slow to start. This PR reduces the reliance on Trusty. As far as I understand it, the random slow start is due to a travis infrastructure issue and is not necessarily isolated to trusty, it's just reported as more common with trusty.

I've also moved the HHVM configuration setting for disabling the JIT before the composer lines. This should also help improve the overall testing speed.

Thanks @photodude

[photodude]

you are welcome.

@photodude: could this change cause that travis build isn't executed?
Merge request wasn't executed. PRs aren't executed... Travis/github integration is enabled.

@zdenekdrahos This change should not cause travis to fail to build. Sounds like a travis connection error (or possibly an issue with how github connects to travis).

I'll add another PR that will specify precise for all other builds rather than relying on the default setting, in case travis changed something. But even with that, you likely need to contact travis about the failures to build.

@zdenekdrahos definitly a travis connection issue. the message continuous-integration/travis-ci — Waiting for status to be reported clearly says travis is not talking to your repo and your repo is waiting to hear from travis.

It's not a build failure, or failure to build it;s a connection issue.
you can see the build status on travis

• https://travis-ci.org/EdgedesignCZ/phpqa/builds
  and the PR status
• https://travis-ci.org/EdgedesignCZ/phpqa/pull_requests

the PR status says the PR builds are not being created, (there is an account setting for that)
it looks like the repo and travis are just not talking. So a connection or account setting issue.

you can see my travis account is building for PR #59

Thanks for you help. I've already contacted the github support.
Because I think that problem is at github side. There are no requests in travis.
